React JS Tutorial for Beginners
What is ReactJS?
ReactJS is one of the most widely popular open-source JavaScript libraries developed by Facebook. It is responsible for managing the view layer for both web and mobile-based applications. The primary use of React is in building reusable UI components.
ReactJS is user-friendly and therefore has a strong foundation and community behind it.
What is the use of ReactJS?
The main feature of ReactJS is developing a User Interface (UI) to improve application speed. The JavaScript virtual DOM, which is faster than the regular DOM, makes it possible to enhance its performance.
A ReactJS application consists of multiple components, where each is responsible for producing a small, reusable part of HTML code. You can nest these components with other ones to build complex applications with simple building blocks.
React’s component and data patterns boost readability and help handle large applications. You can make use of ReactJS on both the client, server-side, and other frameworks.
Why learn React JS?
There are several JavaScript frameworks available, but React is one of the most popular ones among them. The difference between the older frameworks and React is that the former ones use a traditional data flow structure, using the DOM (Document Object Model).
But, what is DOM? A browser creates objects every time you load a web page. Data is added or removed at the back end after any modifications, and every time a new DOM is created for the same page. Hence, memory is wasted unnecessarily due to the repeated procedure, leading to reduced application performance.
To solve the above problem, Facebook invented ReactJS. Although it still follows the traditional data flow structure, it does not directly operate on the browser’s DOM (Document Object Model) but a virtual DOM instead. Therefore, it fixes any DOM changes built and run in the memory itself.
Features of ReactJS:
JSX: It is a JavaScript syntax extension. JSX stands for JavaScript XML. Although it is not necessary to use JSX, it is recommended to use it.
Components: Components are the core of React. They are essential when you are handling the code for large-scale projects.
One-way data-binding: React applies a one-way data-binding or a unidirectional data flow. The advantage of this is that it gives the user better control over the application. Flux ensures the unidirectional flow of data. It increases efficiency by improving the application’s flexibility.
Simplicity: The JSX file in ReactJS simplifies the application.
Performer: React’s performance is excellent. The main reason behind it is that it uses a virtual DOM, unlike the other frameworks.
