1) Why Learn React JS 2023?

Let’s take a look at the major reasons to learn React JS 2023 in detail:

It is a popular and high-Paying IT Job:

To start, React is the popular open-source library used to create robust and dynamic user interfaces. It is efficient for building simple, fast, and scalable frontends.There are more than 220,000 live websites using React. Top industry giants like Apple, Netflix, Paypal, and many started using React JS in their software.

With so many companies using React JS, It is one of the top brands globally. React JS developer salary in India ranges between ₹ 2.2 Lakhs to ₹ 14.0 Lakhs. The average annual salary is ₹ 5.5 Lakhs. Therefore React JS leads to the successful career.

High-performing Applications

Usingoptimizing performance, React JS enable producing high performance applications. It provides significant increase in speed and overall user experience.React uses several clever techniques to speed up the application and lead to a faster user interface. It minimizes the number of DOM operations and to optimizefor performance. 

2) Advantages of React JS

The important advantages of React JS are:

Intuitive

Firstly, ReactJS is extremely intuitive that easily break an app into small components. Each component keeps the specific logic isolated from other components.  It provides interactivity to the layout of any UI. Plus, by saying time, it enables fast and quality assured application development.Updating and Cutting out the actual DOM makes creating UIsmore intuitive and less complex process.

Declarative

To make front end development as a piece of cake for developers, use ReactJS. It allows developers to declaratively describe user interfaces.While making the code simple to read and understand, React takes a lot of heavy lifting for the coding process. React makes interactive UIs by changing the state of the component and updating the DOM virtually.

Components Support

A stand-out benefit of React is its ability to re-use code and components throughout any application. It helps to work smarter as using re-use components across the same application. Reusable components help to maintain a consistent code style. It achieves the overall maintainability of the application. Totally it helps to run on different builds with similar functionality.

JavaScript library

For better JavaScript applications, React is written in JavaScript. It is specifically referred as a library.React is used tobuild user interfaces (UIs)as a tree of small pieces called components. It was made to build full-fledged web applications. Compared with other tools, Developers prefer react to build apps. React component is a mixture of HTML and JavaScript. It captures the logic required to display a small section of a larger UI.

3) Syllabus of React JS

Always, Aspirants prefer learning the React JS using standard syllabus that starts from the basics to advanced concepts. The Syllabus helps to grab the clear knowledge about React. The following basic Knowledge is preferred for the React JS Professionals,

JavaScript,HTML,CSSFunctional programming,Front-end languages

After gaining the basic programming knowledge, start from the React fundamentals such as

React concepts,Virtual DOM,Component lifecycle,Component statefull mobile app development lifecycle,user interface design

Now move on the advanced concepts along withReact Native software and technologies such as Jest, Enzyme, ESLint and much more.

Overview of JSX

The important aspect of React is JSX which is an extension of the React JS environment. JSX is the ReactJS’s syntactic extension. Technically, JSX is the abstract layer created on top of React.createElement() API. JSX is the essential component of the development that allows developers to design apps. It is used to make the process less complex.

Use React.createElement() to build a entire application. It makes the development more efficient and smooth. It is one of the important skills to look in a React JS software developer.

React JS Environment setups

Event Handling in JSX

Event handlers in React JS determine what action is to be taken whenever an event is fired. This includes all events such as button click or a change in a text input. Essentially, event handlers help the users to interact with the React app.

The React onClick event handler enables to call a function and trigger when a user performs an event. Event names are written in camelCase, so the onclick event is written in a React app. React event handlers appear inside curly braces.

React JS is one of the most developmentally important frontend libraries. It has emerged as the future of web creation with versatility and ease.

6) React JS Vs other frameworks/libraries (Angular)

Angular, React, and Vue.js are all JavaScript-based frameworks used to build the front-end part of web applications. When compared with others, React is the more suitable framework for intermediate to advanced JavaScript developers.React Context helps to pass state through the component tree.It is mainly used to manage the theme, language, and other stateful data.

To learn the framework, React is much easier to grasp. It uses its own syntax JSX and JavaScript.React uses a component-based approach with superb results.It provides different tools to develop any kind of apps.

For speeding up the application performance, React use VirtualDocument Object Model. It tends to make changes without affecting the DOM. The updated virtual DOM is easy to modify and re-rendered.

7) Conclusion
