ReactJS Features

As of now, within the developers, ReactJS is gaining much popularity as the best JavaScript framework. It is crucial for the front-end ecosystem.

There are some of the crucial features of ReactJS that are mentioned as follows:

  • JSX
  • Components
  • One-way data binding
  • Virtual DOM
  • Simplicity
  • Performance
Features of ReactJS

Let's elaborate on these features:

JSX

JSX is an acronym of JavaScript XML. It is an extension of the JavaScript syntax. Its syntax is similar to XML or HTML. This syntax is processed into JavaScript Calls of React Framework. It enhances the ES6 so that the texts like HTML can co-exist with JavaScript react code. It is not mandatory to use JSX, but it is advisable to use it in ReactJS.

One-Way Data Binding

ReactJS is designed in a manner that follows the unidirectional data flow or one-way Data Binding. One-way data binding is advantageous as it provides better control throughout the application. When the data flow in another direction, then the additional features are required in it. It happens because the components are thought to be immutable, and the data within them cannot be modified. The pattern Flux helps to keep data unidirectional. It provides more flexibility to the application, which leads to increase efficiency.

Virtual DOM

Virtual DOM is nothing but a representation of actual DOM. It works like one-way data binding. At every modification in the web application, the complete UI is re-rendered in virtual DOM representation. Then, it analyses the difference between the new DOM (which is re-rendered) and the representation of previous DOM. Once it gets completed, real DOM modifies the things that changed. It saves memory and makes the application faster.

Simplicity

As we know, ReactJS uses JSX, which provides simplicity to the application and makes the code understandable. ReactJS follows a component-based approach, which provides the reusability to the code. It makes it easy to learn and use.

Components

ReactJS is made up of components, in which each component has its logic and controls. The components are reusable that helps in maintaining the code when working on large scale projects.

Performance

ReactJS has great performance. Because of this feature, ReactJS becomes much better to compare to other frameworks. Behind this reason, there is a concept of managing virtual DOM. The DOM is nothing but a cross-platform and programming API that deals with HTML, XML, and XHTML. The DOM entirely exists in memory. Because of this, whenever we create a component, we did not write them directly to the DOM; instead of this, we write virtual components that turn into the DOM leads to smoother and faster performance.
