Features of React
1. JSX(JavaScript Syntax Extension)
JSX is a combination of HTML and JavaScript. You can embed JavaScript objects inside the HTML elements. JSX is not supported by the browsers, as a result, Babel compiler transcompile the code into JavaScript code. JSX makes codes easy and understandable. It is easy to learn if you know HTML and JavaScript.
const name="GeekforGeeks";
const ele = <h1>Welcome to {name}</h1>;
2. Virtual DOM
DOM stands for Document Object Model. It is the most important part of the web as it divides into modules and executes the code. Usually, JavaScript Frameworks updates the whole DOM at once, which makes the web application slow. But react uses virtual DOM which is an exact copy of real DOM. Whenever there is a modification in the web application, the whole virtual DOM is updated first and finds the difference between real DOM and Virtual DOM.
In the above-shown figure, when the whole virtual DOM has updated there is a change in the child components. So, now DOM finds the difference and updates only the changed part.
3. One-way Data Binding
One-way data binding, the name itself says that it is a one-direction flow. The data in react flows only in one direction i.e. the data is transferred from top to bottom i.e. from parent components to child components. The properties(props) in the child component cannot return the data to its parent component but it can have communication with the parent components to modify the states according to the provided inputs.
As shown in the above diagram, data can flow only from top to bottom.
4. Performance
As we discussed earlier, react uses virtual DOM and updates only the modified parts. So , this makes the DOM to run faster. DOM executes in memory so we can create separate components which makes the DOM run faster.
Next VS React
JavaScript has become more powerful and popular. It has a vast ecosystem and a large community which is increasing rapidly. React has become the most loved and used JavaScript library among developers to create Single Page Application and Next is an open-source web development React-based framework created by Vercel, which is famous for its unique features such as Server-side rendering and enhanced SEO.
