When to use a Class Component over a Function Component?

  • When handling complex state and lifecycle methods
  • When rendering simple UI components
  • When using Redux
  • When using TypeScript
Class components in React are used when handling complex state and lifecycle methods. They provide additional functionality over function components, such as the ability to use lifecycle methods like componentDidMount and componentDidUpdate, and to maintain internal state. Function components are generally used for rendering simple UI components, while class components are used for more complex functionality.
