React Native is a popular cross-platform mobile development framework that has gained significant traction in recent years. One of the critical components of any mobile application is the ability to store and retrieve data efficiently. React Native provides two main libraries for data storage – React Native MMKV and React Native Async Storage.

In this blog, we will compare these two libraries and explore the benefits of using React Native MMKV.

React Native Async Storage

React Native Async Storage is a popular library for storing data in React Native applications. It offers a simple key-value storage API and uses the AsyncStorage module to save data. AsyncStorage is a persistent, unencrypted, and asynchronous key-value storage system that stores data in a global file system. One of the main drawbacks of AsyncStorage is that it can be slow, especially when dealing with large amounts of data. Additionally, AsyncStorage is asynchronous, which means that you need to use async/await or Promises to access the stored data.

React Native MMKV

React Native MMKV is a more recent addition to the React Native ecosystem. MMKV stands for Mabinogi Mini Key Value, and it was originally designed as a lightweight and efficient key-value storage system for the WeChat app. React Native MMKV brings this efficient and user-friendly storage system to the React Native platform, with direct bindings to the native C++ library through a simple JavaScript API. One of the main benefits of React Native MMKV is its performance. It is up to 30 times faster than AsyncStorage, thanks to its use of C++ code. Additionally, React Native MMKV provides encryption support, which makes it more secure than AsyncStorage.

Comparison of React Native MMKV and React Native Async Storage

Now let’s compare the features of React Native MMKV and React Native Async Storage:

  1. Performance: React Native MMKV is much faster than AsyncStorage, thanks to its use of C++ code. This makes it an excellent choice for applications that require fast and efficient data storage.
  2. Encryption: React Native MMKV provides encryption support, making it a more secure storage solution than AsyncStorage.
  3. API: React Native MMKV offers a more user-friendly API than AsyncStorage, with fully synchronous calls, making it easier to use without async/await or Promises.
  4. Support for objects: React Native MMKV offers support for object storage, making it easier to store complex data structures.
  5. Integration with state management libraries: React Native MMKV integrates seamlessly with popular state management libraries such as jotai, redux-persist, mobx-persist, and zustand-persist-middleware, making it easy to use with existing state management solutions.

Zustand middleware-persist and React Native MMKV

React Native MMKV can integrate with popular state management libraries like Zustand middleware-persist, making it easier to manage and persist application data. With this integration, developers can leverage the power of MMKV’s efficient, fast, and easy-to-use storage capabilities with their existing state management solutions.

Using React Native MMKV with Expo

React Native MMKV is compatible with Expo, but since it is built on top of native modules, it will not work in a typical Expo app. Instead, we need to generate native code, or we can leverage the prebuild feature of Expo.

Conclusion

React Native MMKV is an excellent choice for developers looking for a fast, secure, and user-friendly data storage solution for their React Native applications. With its fully synchronous API, support for object storage, encryption support, and seamless integration with state management libraries, React Native MMKV provides a significant advantage over AsyncStorage. We highly recommend React Native MMKV for any React Native application that requires fast and efficient data storage.

In this complete guide, we’ll walk you through the entire process of building a website, from start to finish. We’ll cover everything you need to know, including:

  • Choosing a domain name and hosting provider
  • Designing and organizing your website
  • Writing content and optimizing for search engines
  • Promoting your website and driving traffic

Let’s get started!

Choosing a Domain Name and Hosting Provider

The first step in building a website is choosing a domain name and hosting provider. Your domain name is your website’s address on the internet, and it’s what people will type into their browsers to visit your site. For example, the domain name of this website is “kodebloc.com

When choosing a domain name, it’s important to choose a name that is memorable and easy to spell. You should also consider whether you want a “.com” or a different top-level domain (TLD), such as “.net” or “.org.”

Once you’ve chosen a domain name, you’ll need to register it with a domain registrar and purchase hosting. Hosting is essentially a service that allows your website to be stored on a server and accessed by users on the internet. There are many hosting providers to choose from, and the one you choose will depend on your needs and budget.

Designing and Organizing Your Website

Now that you have a domain name and hosting set up, it’s time to start designing and organizing your website. This is where you’ll decide on the overall look and feel of your site, as well as how you want to structure the content.

One important consideration when designing your website is how you want it to look on different devices. With the proliferation of smartphones and tablets, it’s essential that your website is responsive, meaning that it looks and functions well on any device.

When organizing your website, you’ll want to consider the structure of your navigation. This is the menu that allows users to move between different pages on your site. A clear and logical navigation structure will help users find what they’re looking for and encourage them to explore your site further.

Top 10 Website Builders

Choosing a website builder or content management system (CMS)

There are many options available for building a website, including website builders like Wix or Weebly, or content management systems like WordPress or Joomla. Each option has its own pros and cons, and the right choice will depend on your needs and technical skills.

A Comparison of Website Builders and Content Management Systems (CMS)

This may involve obtaining an SSL certificate to encrypt data transmitted between your website and visitors’ browsers, or implementing security measures to protect against hacking or other cyber threats.

Analyzing and improving your website’s performance

Once your website is live, you’ll want to track its performance and make improvements as needed. This may involve using tools like Google Analytics to understand how visitors are interacting with your site, and making changes based on this data to improve the user experience and increase conversions.

Writing Content and Optimizing for Search Engines

Once you’ve designed and organized your website, it’s time to start adding content. Content is what will attract visitors to your site and keep them coming back for more. When writing content for your website, it’s important to consider both the needs of your users and the search engines.

To optimize your content for search engines, you’ll want to do keyword research to determine the terms and phrases that people are using to find websites like yours. You can then include these keywords in your content in a natural way, helping search engines understand what your website is about and how it should be ranked.

Promoting Your Website and Driving Traffic

Now that you’ve built your website, it’s time to start promoting it and driving traffic. There are many ways to do this, including:

  • Search engine optimization (SEO): By following best practices for SEO, you can improve your website’s visibility in search engine results pages (SERPs) and attract more organic traffic.

JavaScript Programming Tips Tips & Tricks

From Netscape to Node: The Evolution of JavaScript as a Leading Web Development Language

Reading Time: 4 mins

Introduction

JavaScript is a programming language that was first introduced in 1995. It is a high-level, dynamic, and interpreted language that is widely used in web development to create interactive and engaging web applications. JavaScript is supported by all modern web browsers, making it an essential tool for front-end web development.

In this article, we will explore the history and development of JavaScript, as well as its key features and capabilities. We will also discuss the current state of JavaScript and its future prospects.

History of JavaScript

The history of JavaScript can be traced back to the early days of the internet. In the mid-1990s, Netscape, a leading web browser company at the time, was looking for a way to make its web browser more interactive and dynamic. In response, Netscape developed a new programming language called LiveScript, which was designed to add interactivity to web pages.

LiveScript was first introduced in Netscape Navigator 2.0 in 1995, and it quickly gained popularity among web developers. However, in an effort to make the language more marketable, Netscape changed the name of the language to JavaScript in December of that year. The name was chosen to capitalize on the popularity of Java, which was a popular programming language at the time.

Differences Between JavaScript and Java

Despite the name, JavaScript has no relation to Java. They are two completely separate programming languages with different syntax and capabilities. However, JavaScript does borrow some of its syntax from C, a popular programming language that was developed in the 1970s.

Java is a statically-typed, object-oriented language that is designed to be used for building large-scale enterprise applications. In contrast, JavaScript is a dynamically-typed, interpreted language that is primarily used for building web applications.

One key difference between the two languages is that Java is compiled, while JavaScript is interpreted. This means that in Java, the code is transformed into machine code before it is executed, while in JavaScript, the code is interpreted and executed on the fly by the web browser.

Early Days of JavaScript

In the early days of JavaScript, the language was primarily used to add simple interactive elements to web pages, such as pop-up windows and form validation. However, as the language has evolved, it has become much more powerful and is now capable of building complex web applications.

One of the key features of JavaScript is its ability to run on the client-side, which means that it can be executed by the user’s web browser rather than on a server. This allows JavaScript to create interactive and dynamic web pages without the need for the page to be reloaded.

In addition to running on the client-side, JavaScript can also be run on the server-side using a runtime environment such as Node.js. This allows developers to use JavaScript to build full-stack web applications, handling both the front-end and back-end components of the application.

Rise of JavaScript Frameworks

As JavaScript has become more powerful and widely used, a number of frameworks and libraries have been developed to make it easier for developers to build web applications. Some of the most popular JavaScript frameworks include Angular, React, and Vue.js.

These frameworks provide a set of pre-built components and tools that make it easier to build complex web applications. They also provide a structure and set of best practices for developing and maintaining large-scale web applications.

Current State of JavaScript

Today, JavaScript is one of the most popular programming languages in the world. It is supported by all modern web browsers, making it an essential tool for front-end web development. In addition to its use in web development, JavaScript is also used in the development of mobile apps, desktop applications, and games.

In recent years, the popularity of JavaScript has only continued to grow. According to the TIOBE Index, which ranks programming languages based on their popularity, JavaScript has consistently been one of the top three most popular languages since 2003. In 2021, JavaScript was ranked as the second most popular programming language, behind only Java.

One of the reasons for JavaScript’s popularity is its versatility. It can be used to build a wide range of applications, from simple websites to complex web-based applications. In addition, JavaScript has a large and active community of developers, who contribute to the language by developing new libraries, frameworks, and tools.

Another factor contributing to the popularity of JavaScript is its ease of use. It is a high-level language, which means that it is relatively easy to learn and understand, even for those with little programming experience. This has made it a popular choice for beginners and experienced developers alike.

Finally, the widespread adoption of JavaScript by major tech companies has also contributed to its popularity. Many of the biggest names in tech, including Google, Facebook, and Microsoft, use JavaScript in their products and services. This has further cemented its position as a leading programming language.

Future of JavaScript

Given its widespread popularity and versatility, it is clear that JavaScript will continue to be a major player in the world of programming and web development for the foreseeable future.

One area where JavaScript is expected to see significant growth is in the field of mobile app development. Many developers are already using JavaScript frameworks like React Native to build cross-platform mobile apps that can run on both iOS and Android.

In addition to its use in mobile app development, JavaScript is also expected to play a key role in the development of Internet of Things (IoT) devices. As more and more devices become connected to the internet, the demand for developers with JavaScript skills is likely to increase.

Conclusion

In conclusion, JavaScript is a powerful and popular programming language that is widely used in web development to create interactive and dynamic web applications. It has a rich history, and it continues to evolve and grow in popularity today. From its humble beginnings as LiveScript to its current status as one of the most widely used programming languages in the world, JavaScript has come a long way. And with its continued growth and evolution, it is clear that JavaScript will remain a key player in the world of programming and web development for years to come.

JavaScript Programming Tips Tips & Tricks

The 5 most useful Javascript tips for web developers

Reading Time: 7 mins
Photo by AltumCode

If you’re a web developer, chances are you’re always on the lookout for ways to improve your workflow and get things done faster. Javascript is a versatile language that can be used for front-end, back-end, and even full-stack development.

In this article, we’ve compiled a list of the 10 most useful Javascript tips for web developers, including both beginners and experienced developers. From tips on code organization to performance optimization, these tips will help you take your web development skills to the next level.

1. Use strict mode

In JavaScript, “strict mode” is a way to opt-in to a restricted variant of JavaScript. Strict mode makes it easier to write “secure” JavaScript by eliminating some of the “silent errors” that are possible in regular JavaScript.

To use strict mode, you just need to include the string “use strict” at the top of your JavaScript file or at the top of a function. For example:

"use strict";

function myFunction() {
  // code here is executed in strict mode
}

Alternatively, you can put the string “use strict” at the top of a function to enable strict mode only for that function:

function myFunction() {
  "use strict";

  // code here is executed in strict mode
}

Here are some of the main changes that strict mode makes to JavaScript:

  • Strict mode eliminates some JavaScript silent errors by changing them to throw errors. For example, in strict mode, assigning a value to a read-only property will throw an error, whereas, in regular JavaScript, it would just fail silently.
  • Strict mode prohibits the use of certain syntax that is confusing or problematic. For example, in strict mode, you can’t use a variable named “eval” or “arguments”, and you can’t delete variables or functions.
  • Strict mode makes it easier to write “secure” JavaScript by disabling features that can be used to inadvertently create insecure code. For example, in strict mode, you can’t use the same name for a function parameter and a variable in the same function.

It’s worth noting that strict mode is only a restricted variant of JavaScript, and it doesn’t add any new features to the language. However, many developers find that strict mode helps them write more reliable and secure code, so it’s often used in production applications.

2. Declare variables with ‘let’ and ‘const’

In JavaScript, `let` and `const` are two ways to declare variables. Both are used to declare variables that can be reassigned, but there are some key differences between the two.

`let` is used to declare variables that can be reassigned. This means that the variable can be initialized more than once and can be changed later on. It is also block-scoped. This means that variables declared with `let` are only available within the block they were declared in. For example, if a `let` variable is declared within a for loop, it will only be available within that for a loop.

let x = 10;
console.log(x); // output: 10
x = 20;
console.log(x); // output: 20

`const` is used to declare variables that cannot be reassigned. This means that the variable can only be initialized once and cannot be changed later on. Like `let`, `const` is block scoped and is not hoisted.

const y = 10;
console.log(y); // output: 10
y = 20; // this will throw an error

It’s worth noting that while the value of a const variable can’t be reassigned, the value itself may still be mutable. For example, if you assign an object to a const variable, you can still modify the properties of that object:

const z = { name: 'John' };
console.log(z); // output: { name: 'John' }
z.name = 'Jane';
console.log(z); // output: { name: 'Jane' }

However, if you try to reassign the entire object to a new value, you’ll get an error:

const z = { name: 'John' };
console.log(z); // output: { name: 'John' }
z = { name: 'Jane' }; // this will throw an error
Why you should avoid using the ‘var’ keyword

Variable declarations using the `var` keyword are subject to `hoisting`. This can lead to unexpected results, particularly in cases where a `var` declaration is used within a loop or an `if` statement. `let` and `const` declarations are both block-scoped. This means that they can only be declared within the block in which they are used. This can help to spot bugs and makes your code more robust.

So which one should you use ‘let’ or ‘const’?

In general, it’s a good practice to use const for variables that don’t need to be reassigned, and use let for variables that do. This can help make your code more readable and easier to understand, as it clearly communicates the intended behavior of the variables.

For example, if you have a variable that stores a value that won’t change throughout the lifetime of your program, you should use const to declare that variable. For example:

const PI = 3.14;

On the other hand, if you have a variable that needs to be reassigned at some point, you should use let to declare that variable. For example:

let counter = 0;
counter += 1;
console.log(counter); // output: 1
counter += 1;
console.log(counter); // output: 2

It’s worth noting that there may be cases where you want to use let even for variables that don’t need to be reassigned. For example, if you’re using a for loop to iterate over an array, you’ll typically use a let variable to store the loop index:

const names = ['John', 'Jane', 'Mike'];
for (let i = 0; i < names.length; i++) {
  console.log(names[i]);
}

In this case, the value of i does change with each iteration of the loop, but it’s not intended to be used outside of the loop. In cases like this, using let is fine, as it clearly communicates that the variable is only meant to be used within a specific block of code.

Use template literals

Template strings, available in ES6, offer a convenient way to insert variables and expressions into strings. This eliminates the need for concatenation, making it possible to create complex strings with dynamic elements.

The `template string` syntax is denoted by the backtick (`) character, and they can contain placeholders for expressions, which are represented by ${expression}.characters. They can be used for multi-line strings, string interpolation with embedded expressions, and special constructs called tagged templates.

For example, we can write:

`I'm a template string!`
Interpolating

Interpolating variables and expressions is a process of substituting values into a string or expression, this is often referred to as string interpolation. In JavaScript template literals, we insert a variable or expression by adding a dollar sign $ and curly braces {} into the string. This is a much more efficient method than the alternative in old JavaScript, where we would have to concatenate strings like the following:

// Concatenation using template literals

const name = 'Alex';
const age = 25;

const greeting = `Hello, my name is ${name} and I am ${age} years old.`;

console.log(greeting); // "Hello, my name is Alex and I am 25 years old."
// Old method of concatenation

const name = 'Alex';
const age = 25;

const greeting = 'Hello, my name is ' + name + ' and I am ' + age + ' years old.';

console.log(greeting); // "Hello, my name is Alex and I am 25 years old."

As we can see, the old concatenation syntax can easily lead to syntax errors when working with complex variables and expressions. Template strings are a great improvement in this area.

Multi-Line

Template literals can also contain multi-line strings and string interpolation. Here is an example:

const multiline = `This is a
multi-line string
that contains string interpolation: ${name}`;

console.log(multiline);

This will output the following string:

This is a
multi-line string
that contains string interpolation: Alex

4. Destructuring assignment

The destructuring assignment syntax is a useful JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables. This can be a very convenient way to extract data from structures that are nested or otherwise complex and can make code much more readable.

For example, if the object has properties named name and age, you can assign the object’s value for the name to the first variable and it’s for age to the second.

// Expressions

let name, age;
[name, age] = ['Alex', 25];

console.log(name); // expected output: Alex
console.log(age); // expected output: 25
Array destructuring

Destructuring arrays in JavaScript gives you a great way to extract data from arrays into individual variables. This can be especially helpful when working with APIs that return large amounts of data. By destructuring the array, you can access the data more easily and work with it more efficiently.

// Array destructuring

const x = [1, 2, 3];

const [one, two, three] = x;

console.log(one); // 1
console.log(two); // 2
console.log(three); // 3
Object destructuring

Javascript object destructuring is a powerful tool that can be used to simplify working with objects. It allows you to extract data from an object and assign it to variables. This can be very useful when working with data structures such as JSON objects.

// Object destructuring

const user = {
  name: 'Alex',
  age: 25,
};

const { name, age } = user;

console.log(name); // 'Alex'
console.log(age); // 25

5. Arrow functions

Another impressive feature of Javascript is the arrow function. An arrow function is a shorter syntax for writing a function expression. Arrow functions are anonymous and do not have their own `this` value. They are best suited for non-method functions, and they cannot be used as constructors.

Arrow functions are a great way to create readable and maintainable code compared to regular functions. They were introduced in the ES6 version of JavaScript. Arrow functions get executed after all the function’s parameters have been processed, making them great for working with data.

// Regular function

let add = function(x, y) {
   return x + y;
}

// Arrow functions
let add = (x, y) => x + y;

Here are some additional features of arrow functions:

  • If an arrow function has a single argument, you can omit the parentheses around the argument list. For example, (x) => x * x can be written as x => x * x.
  • If an arrow function has a single statement in its body, you can omit the curly braces and the return keyword. The value of the statement is returned implicitly. For example, x => x * x is equivalent to x => { return x * x; }.
  • If an arrow function has no arguments, you must include an empty pair of parentheses. For example:
() => console.log('Hello!').

Conclusion

Whether you’re a beginner or an advanced Javascript developer, these tips are sure to help you improve your workflow and become a better developer. Try implementing some of these techniques in your projects, and you’ll see how much time they save.
