React brings multiple benefits to the developers, making it a perfect choice than other frameworks. If you’re new to ReactJS framework or just looking to work on the core concepts, this blog post will give you an introduction to features. We’ll be covering them in detail in this blog:

What is ReactJs?

React is a JavaScript library created to build smooth and interactive user interfaces for web applications. It is an open-source, front-end library used for the application’s view layer. In Model View Controller (MVC) architecture, the view layer reveals the app looks and feels. React was developed & currently managed by Facebook. If you want to Hire ReactJs Developer reach out to a reputed development company for the latest services.

Why choose ReactJs?

React’s popularity today has eclipsed that of all other front-end development frameworks. Here is why:

1. Smooth creation of dynamic apps

ReactJs makes it simpler to build dynamic web applications because it needs less coding and offers more functionality, as opposed to JavaScript, where coding often gets complex very quickly.

2. Advanced Performance

React uses Virtual DOM, thereby building web applications faster. Virtual DOM compares the components’ earlier states and updates only the items in the Real DOM that were changed, apart from updating all of the components like the conventional web applications.

3. Reusable Components

Components are the building blocks of any React application, and a single app usually includes multiple components. These components have their logic and controls, and they can be reused throughout the application, which in turn simply lowers reduces the application’s development time. This is a great asset to ReactJs Web Development Service and brings remarkable business results.

4. Unidirectional Data Flow

React follows a unidirectional data flow. This means that when building a ReactJs app, developers often nest child components within parent components. Since the data flows in a single direction, it becomes simpler to debug errors and know where a problem occurs in an application at the moment in question.

Features of ReactJs Framework

1. JavaScript Syntax Extension

JSX is a syntax extension used with React to describe what the user interface appears like. By using JSX, HTML structures can be written in the same file that includes JavaScript code. This makes the code simpler to learn and debug, as it avoids the usage of complex JavaScript DOM structures.


const name = ‘Simplilearn’;

const greet = <h1>Hello, {name}</h1>;

The above code shows how JSX is implemented in React.

2. Components

Functional Components: These components are stateless and only include a render method. They may derive data from other components as properties.

function Greeting(props) {

return <h1>Welcome to {props.name}</h1>;


Class Components: These components easily hold and manage their state and have a separate render approach for returning JSX on the screen. They are also termed as stateful components, as they can have a state.

class Greeting extends React.Component {

render() {

return <h1>Welcome to {this.props.name}</h1>;



3. State

The state is a built-in React object that contains data or information about the component. A component’s state can change over time; whenever it changes, the component re-renders. The change in state can happen as a response to user action or system-generated events, and these changes mention the component behavior and how it will render. You can Avail ReactJs Development Services from the industry experts to get desired business benefits.

class Greetings extends React.Component {

state = {

name: “World”


updateName() {

this.setState({ name: “Simplilearn” });


render() {








ReactJS Prerequisites

Here are some of the concepts that you should be aware of, to one degree or another:

  • Programming concepts include functions, objects, arrays, and to a lesser extent, classes
  • Basic knowledge of JavaScript & HTML

Frequently Asked Questions

1. Why is Reactjs used to build an application?

JavaScript Friendly and Facebook allow the use of JSX, a syntax extension. It allows you to combine the functionalities of JavaScript and HTML. As a developer, you can now focus on creating individual components and then combine them. This allows for the easy development of high-volume applications.

2. Why is ReactJS so popular?

The core objective of ReactJS is to provide the best possible rendering performance. Its strength comes from the focus on individual components. Instead of working on the entire web app, ReactJS allows a developer to break down the complex UI into simpler components.

3. Is ReactJs better than Angularjs?

Prompt rendering is among the best features of React that gives a significant edge over Angular. The core difference between Reactjs and Angularjs is that React is JS-centric, while Angular 2 remains HTML-centric. JavaScript is far more robust, than HTML that makes ReactJs far more simple, focused and consistent.

4. Do you assure about security & confidentiality of the idea?

Yes, we sign a strict NDA to protect your application idea & data. Hence, we ensure complete security and privacy of your application development project.

5. What is the development cost of ReactJs web application?

The development cost depends on the complexity, features, size and experienced of the developers. The whole process is transparent and proper details are shared accordingly on regular basis.
