Hello and welcome to this ReactJS Tutorial for Beginners and Professional Software Developers. This React Tutorial will take you through most of the practical applications of React. In this React Tutorials for Beginners and Professionals Series, we will cover all the concepts of React JS with Real-Time Applications. You will learn from the very basic to advanced features of React JS as you progress in this Course.

This ReactJS Tutorial is for whom?

This ReactJS Tutorial is prepared for those developers who want to make a career in developing front-end web applications. This React JS Tutorial is designed for Students, Beginners, and Professional Software Developers who want to learn and enhance their knowledge of React step by step, from the very basic to the advanced level concept using Real-Time Examples. 

What is ReactJS?

ReactJS, commonly referred to as React, is an Open-Source JavaScript library for building user interfaces or UI components. It was developed by Facebook and is maintained by Facebook and a community of individual developers and companies.

React can be used as a base for developing single-page or mobile applications. However, React is only concerned with rendering data to the DOM (Document Object Model), so creating applications usually requires additional libraries for state management and routing.

In the Industry, React JS is one of the most popular JavaScript Front-End libraries with a strong foundation and a large community. React JS is a Declarative, Efficient, and Flexible JavaScript library for building reusable UI components.

Key Features of ReactJS:

• Declarative: React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable and easier to debug.
• Component-Based: Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.
• Learn Once, Write Anywhere: React doesn’t mandate the use of specific technologies, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using React Native.
• JSX: JSX is a syntax extension to JavaScript. It is used with React to describe what the UI should look like. JSX may remind you of a template language, but it comes with the full power of JavaScript.
• Virtual DOM: React creates an in-memory data structure cache, computes the resulting differences, and then efficiently updates the browser’s displayed DOM. This process is known as reconciliation.
• Optimized for Performance: React implements several clever techniques to minimize the amount of costly DOM operations required to update the UI.

Who Developed ReactJS?

React was developed and released by Facebook (Currently called META). React JS was created by Jordan Walke, who was a software engineer at Facebook. Facebook is continuously working on the React library and enhancing it by fixing bugs and introducing new features. Facebook developed ReactJS in 2011 in its newsfeed section, but it was released to the public in the month of May 2013.

Why You Should Learn ReactJS?

Learning ReactJS is beneficial for several reasons, especially if you’re interested in web development:

• High Demand for React Developers: ReactJS is widely used for building user interfaces, especially in web applications. Many companies, including large tech giants, use React for their products, creating a high demand for skilled React developers.
• Component-Based Architecture: React’s component-based architecture makes it easy to reuse code and manage state across large applications. This modularity enhances code maintainability and makes it simpler to collaborate on large projects.
• Strong Community Support: As an open-source library, React has a large and active community. This results in a wealth of resources for learning, troubleshooting, and staying updated with the latest trends and best practices.
• Efficient Performance: React uses a virtual DOM (Document Object Model) that optimizes rendering performance. This makes it an excellent choice for high-performance applications and dynamic user interfaces.
• Flexibility and Versatility: React can build various applications, from small-scale single-page applications to large, complex web applications. Its flexibility also extends to mobile app development with React Native.
• Ease of Learning: Compared to other front-end frameworks, many developers find React easier to learn due to its simplicity and focused design. This is particularly beneficial for new developers or those transitioning from other technologies.
• Integration with Modern Web Development Tools: React integrates well with other modern web development tools and technologies, such as Redux for state management and various backend technologies (like Node.js).
• Career Advancement: Knowledge of ReactJS can significantly boost your career prospects in web development, as it’s a skill set that’s in high demand and often well-compensated.
• Innovative Ecosystem: The ecosystem around React, including libraries like Redux and React Router, allows for building rich, interactive web applications with less effort.
• Forward-Looking: React is maintained by Facebook and a community of independent developers, ensuring that it stays up-to-date with the latest advancements in web development.

Prerequisites to Learn ReactJS:

To learn ReactJS effectively, it’s important to have a solid foundation in several key areas:

• HTML and CSS: Understanding the basics of HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) is crucial since React is used to build user interfaces for the web. Familiarity with HTML tags, attributes, and basic page layout, along with CSS styling, positioning, and responsive design principles, is necessary.
• JavaScript Fundamentals: React is a JavaScript library, so a strong grasp of JavaScript is essential. This includes understanding variables, data types, functions, arrays, objects, loops, conditionals, ES6 features (like arrow functions, template literals, destructuring, spread/rest operators), and asynchronous programming concepts like promises and async/await.
• Basic Understanding of the Document Object Model (DOM): Since React manipulates the DOM to render UI components, knowledge of the DOM, how it works, and how JavaScript can be used to interact with it is important.
• JavaScript Object Notation (JSON): Many React applications interact with APIs or back-end data structures that use JSON. Understanding how to work with JSON, including parsing and formatting, is useful.
• Node.js and npm (Node Package Manager): While Node.js is not directly used in writing React code, familiarity with it and npm is important for setting up a React development environment, managing packages, and understanding the ecosystem.
• Command Line Interface (CLI): Basic command-line skills are helpful for setting up projects, running development servers, and using build tools.
• Basic Understanding of Web Development Concepts: This includes requests and responses, client-server architecture, and the basics of HTTP/HTTPS.
