Class components and functional components offer different approaches to defining components in React, each with unique features and uses.
โ ๐๐ฅ๐๐ฌ๐ฌ ๐๐จ๐ฆ๐ฉ๐จ๐ง๐๐ง๐ญ๐ฌ: Class components extend React.Component, and include a render() method to return JSX. They manage state internally using this.state and this.setState(). Lifecycle methods like componentDidMount and componentDidUpdate provide hooks for executing code at specific points in the componentโs lifecycle. Methods often need to be bound to the component instance or use arrow functions.
โ ๐ ๐ฎ๐ง๐๐ญ๐ข๐จ๐ง๐๐ฅ ๐๐จ๐ฆ๐ฉ๐จ๐ง๐๐ง๐ญ๐ฌ: Functional components are simpler and use functions to return JSX. They handle state and lifecycle events using hooks such as useState and useEffect. Thereโs no need for this binding, making them easier to read and test. Functional components are preferred for their concise syntax and the ability to leverage hooks for powerful features.
Understanding the distinction between class and functional components helps in choosing the right approach for your React applications, with functional components being the modern standard due to their simplicity and effectiveness.
