What are the Features of ReactJS?

 

React Js

ReactJS is a JavaScript library developed by Facebook for constructing better UI/UX designs for online and mobile applications. It allows developers to build dynamic, interactive applications. An open-source, component-based front-end library is called React. The UI design is the work of React. It simplifies code debugging by breaking it up into components. This blog will explore “What are the Features of ReactJS?”. Join the React JS Training in Chennai and master building dynamic and interactive web applications.

Features of ReactJS

Below are the features of ReactJS:

  • JSX (JavaScript Syntax Extension)
  • Virtual DOM
  • One-way data binding
  • Performance
  • Extensions
  • Conditional statements
  • Components
  • Simplicity

Let’s understand each of them in depth.

JSX(JavaScript Syntax Extension)

JavaScript and HTML are combined to form JSX. The HTML elements can contain JavaScript objects. The Babel translator transforms the code into JavaScript because browsers do not support JSX. JSX simplifies and clarifies the code. Learning this is easy if you are familiar with HTML and JavaScript.

Virtual DOM

  • The DOM stands for document object model. It runs the code and divides it into modules, making it the most essential web part. JavaScript Frameworks often update the DOM simultaneously, slowing down the online application. React uses virtual DOM, an exact duplicate of real DOM. Whenever a web application changes, it first updates the complete virtual DOM to differentiate between the real DOM and the virtual DOM. When DOM notices the difference, it updates the area that has just changed while leaving the remainder unmodified.
  • As mentioned earlier, React utilizes a virtual DOM and updates only the modified parts, thereby accelerating DOM performance. Faster DOM execution leads to the creation of more independent components in memory.

One-way Data Binding

One-way data binding, the name itself, says it is a one-directional flow. React flows data in only one direction, transferring data from parent to child components, i.e., from top to bottom. The properties(props) in the child component cannot return the data to its parent component. Still, they can communicate with the parent components to modify the states according to the provided inputs. Join the React JS Online Course and learn the fundamentals of this popular JavaScript library, create reusable components, and harness the power of one-way data binding for seamless UI development.

Extension

React offers a wide variety of extensions to build comprehensive UI applications. It offers server-side rendering and facilitates the creation of mobile apps. React has extensions like Flux, Redux, React Native, etc., that make it easier to make a UI that looks excellent.

Conditional Statements

  • Conditional statements can be written using JSX. The conditions specified inside the JSX display the data in the browser. Conditional rendering allows you to decide what to show to the user based on the state or props of your components.
  • Due to its component-based architecture, React.js separates the website into numerous components. The UI design includes each component, each with its logic and design. JavaScript component logic is simple to execute faster and reuse.

Simplicity

React.js employs a component-based architecture and uses JSX, a blend of HTML and JavaScript, to improve code reusability. It has less code and makes it simpler to comprehend and debug.

These features make React for creating user interfaces for web and mobile applications. It excels at building modern, interactive, and dynamic front-end applications. ReactJS has become the industry standard for building dynamic, high-performance web applications, and the React JS Course in Chennai is designed to make you a proficient React developer.
