What & Why We Should Use ReactJS

The most widely used front-end JavaScript library for building Web applications is React.js. There are several ways to refer to React.js, including React.js and just React. Reactjs is used by most Fortune 500 firms. Learn more about React.js (also known as React or Reactjs) in this article, along with the advantages it has over other JavaScript frameworks like Angular.

 

React.js: What is it?

An open-source JavaScript package called React.js is used to create user interfaces for single-page applications. It manages the view layer for both online and mobile applications. Reusable UI components may also be made using React. Jordan Walke, a software engineer for Facebook, developed React at first. In 2011 and 2012, Facebook's newsfeed and Instagram.com both used React for the first time.

With the aid of React, programmers may build web applications that can modify data without refreshing the page. React's primary goals are to be quick, scalable, and easy to use. It only functions with the application's user interfaces. This relates to the MVC template's view. It can be combined with other JavaScript frameworks or libraries, such as AngularJS in MVC.

 

Simply React or React.js are other names for React JS.

 

What features does React.js have? 

Let's examine some of React's key attributes in more detail.

> Among the React.js properties are the following

> Declarative programming is used in React.js.

> React.js is easy to use.

> React.js is based on components.

> React.js allows for server-side

> React.js is a big library.

> React.js is quick.

> Learning React.js is simple.

 

JSX

React uses JSX for templating rather than standard JavaScript. JSX is a straightforward JavaScript that supports HTML quoting and renders subcomponents using this HTML tag syntax. React Framework JavaScript calls are generated from HTML syntax. We can also use the original JavaScript language.

 

React Native

Facebook launched React's native libraries in 2015, bringing the react architecture to native apps for IOS, Android, and UPD.

React-native is a framework for creating mobile apps that uses only Javascript. It utilises React's identical concept and enables you to use/incorporate a robust mobile UI library/declarative components. The essential UI building pieces used by most iOS and Android apps are also used here. The ability to use components written in Objective-C, Java, or Swift is the best feature of react-native.

 

Data flow in one direction

In React, a collection of immutable values are supplied as properties in the HTML tags of the component renderer. The component cannot alter any properties directly, but it can send a callback function to which we can make changes. The phrase "properties flow down; actions flow up" refers to the entire process.

 

Object Model for Virtual Documents

In-memory data structures are created by React, which computes the changes made before updating the browser. As opposed to react library, which only renders components that really change, this permits a special feature that lets the programmer to code as though the entire page is rendered on each update.

 

Why React?

The primary query that now confronts us is "why use React?" There are a tonne of open-source systems, like Angular, that make developing front-end web applications simpler. Let's quickly examine React's advantages over competing technologies or frameworks. It's challenging to dedicate time to learning a new framework when the front-end world is constantly evolving, particularly when that framework may prove to be fruitless in the long run. So I advise checking out React if you're seeking for the next best thing but are feeling a little bit confused in the framework jungle.

 

1. Simplicity

It's just easier to understand ReactJS right immediately. React is incredibly easy to understand, build a professional online (and mobile applications), and support thanks to its component-based architecture, well-defined lifecycle, and use of simply plain JavaScript. React makes use of a unique syntax called JSX that enables you to combine HTML and JavaScript. Although JSX is significantly simpler to use, it is not necessary; developers can still write in ordinary JavaScript.

 

2. simple to learn

React is simple to grasp for anyone with a foundational background in programming, in contrast to Angular and Ember, which are touted to as "Domain-specific Languages," suggesting that they are challenging to master. You only need a foundational understanding of CSS and HTML to react.

 

3. Native Method

Mobile apps can be developed with React (React Native). Additionally, React is a staunch supporter of reuse, therefore considerable code reusability is encouraged. We can therefore create IOS, Android, and Web applications all at once.

 

4. Binding Data

One control point—the dispatcher—manages the flow of data to components in React using one-way data binding and the Flux application architecture. Large ReactJS apps with independent components are simpler to debug.

 

5. Performance

There is no notion of a built-in dependency container in React. To automatically inject dependencies, you can utilise Browserify, Require JS, EcmaScript 6 modules that we can use with Babel, and ReactJS-di.

 

6. Testability

Testing ReactJS applications is quite simple. React views can be thought of as functions of the state, allowing us to control the state we pass to the ReactJS view and observe the results and any actions, events, functions, etc. that are triggered.

 

Conclusion

We believe you now understand what and why we should use React JS as an excellent framework.

React is a top-notch framework that is deserving of your attention, just as Angular.
