Key Features of ReactJS
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.
