Higher order components
In React, a Higher Order Component (HOC) is a function that takes a component and returns a new one with added props or behavior. Similar to higher order functions in JavaScript, HOCs are used to reuse component logic throughout an application. They enable developers to enhance existing components with new props without altering the original component code, thus avoiding unnecessary rewriting.
Example : This example demonstrates the implementation of higher order components in React.
Javascript
// App.js import React from 'react' ; import HigherOrder from './HigherOrder' ; function App(props) { return <h1>{props.newprop}</h1> } export default HigherOrder(App) |
Javascript
// HigherOrder.js function HigherOrder(OldComponent) { return function NewComponent(props) { return <OldComponent {...props} newprop= "I'm the newly added prop" />; }; } export default HigherOrder; |
Output :
React JS Component Composition
Component composition in React involves the inclusion of one or more components in a single component, where each sub-component can further consist of additional components. Components in React are building blocks that are used to create user interfaces (UIs).
