  • What is ReactJS? The Important Features of ReactJS



    React was created by Jordan Walke, a software engineer who worked at Facebook. It is a JavaScript library that can be used for developing fast, dynamic and interactive interfaces for mobile and website applications. It is used for developing single web page applications, where the data can reflect instantly.

    ReactJS is a Component-based, Open-Source and Front-end library, which is only responsible for the application’s view layer. Join React JS Training in Chennai, and learn more about the advantages and the features of the ReactJS.

    Among web developers, ReactJS is one of the best JavaScript Frameworks that plays an important role in the front-end ecosystem.

    Some of the important features of ReactJS are: 

    • Components
    • JSX
    • Virtual DOM
    • One-way Data Binding
    • Performance
    • Simplicity.

    JSX-JavaScript Syntax Extension

    JSX is the JavaScript Syntax Extension. It is an HTML or XML syntax that is used by ReactJS. This syntax is implemented into JavaScript calls of the framework of React. With the help of JSX, the HTML structure is written in a similar file, which contains JavaScript Code. This makes understanding and debugging of the code simpler, it can also avoid the complicated JavaScript DOM structures.

    Components

    The applications of ReactsJS is created with multiple components. These components are reusable. Every component has its limitations. When you are working on large scale projects, these components help to support the code.

    One-way Data Binding

    ReactsJS is designed to the extent that it can support One-way data binding or Unidirectional dataflow. The main advantage of one-way data binding is, it provides good control throughout the application.

    Sometimes the flow of data is in another direction, and that time it needs extra features. As the components should be permanent and the data inside should not be changed.

    Flux is a programming pattern that can support keeping your data in a unidirectional way. So that the applications are more flexible and increase efficiency.

    Virtual DOM

    The virtual DOM object is a perfect description of the original DOM object. The virtual DOM acts like one-way data binding. The complete UI is re-rendered in virtual DOM representation if any changes occur in the web application.

    It compares the difference between the new DOM and previous DOM representation. Once the comparison has been done, the real DOM will update the changes. The application will run fast and there is no memory wastage.

    Simplicity

    ReactJS applies the JSX file that executes the application so easy and helps to understand the code completely. The ReactJS is a component-based approach, it can reuse the code when it is required. So that it can be used and learned simply.

    Performance

    ReactJS performs efficiently. It is applied to VDOM, so the web application will operate much faster than the alternate front-end frameworks. React divides the complex user interface into unique elements. To increase the development time, multiple users can work on each element simultaneously.
