ReactJS Tutorial

This ReactJS tutorial includes the most recent updates up to version 18.2.0, covering everything from basic to advanced topics. React is the most recommended JavaScript library to learn currently due to its core features and large community support.

What is ReactJS?

ReactJS is an open-source JavaScript library used for building dynamic and interactive user interfaces (UIs). It was developed and is maintained by Facebook, which continues to enhance the library by fixing bugs and introducing new features.

Who Should Learn ReactJS?

This tutorial is designed for beginners and professionals aspiring to build a career in front-end web development. It helps you get comfortable with React concepts through practical examples.

Why Learn ReactJS?

There are several reasons to learn ReactJS, such as:

  • Ease of Use: ReactJS uses the concept of Components, reducing the amount of code needed while increasing reusability.
  • Multiple Module Support: ReactJS has many modules that make development faster, scalable, and manageable.
  • Multiple App Development: React allows you to build web pages, web apps, mobile apps, and even VR apps. Popular websites like Airbnb, Cloudflare, Facebook, and Instagram use ReactJS.
  • Easy Migration: With React's easy learning curve, migrating from other technologies becomes smoother.
  • Large Community: ReactJS has a vast community that can help solve issues, debug code, and offer learning resources.

ReactJS Example Code

Below is a sample ReactJS code snippet:

  
import React from 'react';
import ReactDOM from 'react-dom/client';

function Greeting(props) {
  return <h1>Welcome to TutorialsPoint</h1>
}

const container = document.getElementById("root");
const root = ReactDOM.createRoot(container);
root.render(<Greeting />);

Features of ReactJS

ReactJS plays a critical role in the front-end ecosystem. Some of its notable features include:

  • Virtual DOM: React uses a Virtual DOM to optimize performance. It compares changes in the virtual DOM with the real DOM and only updates the differences.
  • Reusable Components: Components in React are reusable. You can create a component once and reuse it wherever needed.
  • One-Way Data Binding: One-way data binding ensures data flows in one direction, simplifying data handling and reducing complexity.

Prerequisites to Learn ReactJS

Before diving into ReactJS, you should have a basic understanding of HTML, CSS, and JavaScript.

Getting Started with ReactJS

To begin with ReactJS, it's important to first grasp the fundamentals. As you go through this tutorial, try to code along and create projects to better understand the concepts.

Components in ReactJS

Components are the building blocks of React applications. They represent small chunks of the user interface.

  • Using Components
  • Nested Components
  • Component Collection
  • Components with Properties
  • Component Lifecycle
  • Event-Aware Components
  • Stateless Components
  • Layout Components

State in ReactJS

State refers to the dynamic properties of a React component. It allows React to update and render UI based on user interactions or changes in data.

  • ReactJS State Management
  • State Management through Hooks

ReactJS Hooks

Hooks are functions that give you access to React state and lifecycle events. Some important hooks include:

  • useState Hook
  • useEffect Hook
  • useContext Hook
  • useRef Hook
  • useReducer Hook
  • useCallback Hook
  • useMemo Hook
  • Custom Hooks

ReactJS Props

Props allow data to be passed between components. They are essential for interaction between components, as states are private to each component.

Other Important Topics in ReactJS

Here are some additional topics in ReactJS you should explore:

  • ReactJS Pagination
  • ReactJS Lists
  • ReactJS Keys
  • ReactJS Router
  • ReactJS Redux
  • ReactJS Animation

ReactJS Jobs and Salary

ReactJS developers are in high demand. Companies like Facebook, Instagram, and Airbnb hire ReactJS developers. The salary range for a ReactJS developer in India is between ₹1.5 Lakhs to ₹16.0 Lakhs, with an average annual salary of ₹7.3 Lakhs.
