The React lifecycle refers to the process of a component being instantiated to being destroyed, during which React provides some hooks that allow specific logic to be executed, such as preparing tasks before the component is rendered on the page or cleaning up tasks before the component is destroyed. Common React lifecycles include:<\/p>\n

    \n
  1. componentWillMount: called when the component is about to be mounted on the page<\/li>\n
  2. componentDidMount: called after the component is mounted on the page<\/li>\n
  3. componentWillReceiveProps: called when the component receives new props.<\/li>\n
  4. shouldComponentUpdate: Determine whether the component needs to be re-rendered when it receives new props or state.<\/li>\n
  5. componentWillUpdate: Called when the component is about to update.<\/li>\n
  6. componentDidUpdate: called after the component has finished updating.<\/li>\n
  7. componentWillUnmount: called when the component is about to be destroyed.<\/li>\n<\/ol>\n

    New lifecycle methods were introduced in React version 16.3, including:<\/p>\n

      \n
    1. The getDerivedStateFromProps method is called when a component receives new props, serving as a replacement for componentWillReceiveProps.<\/li>\n
    2. getSnapshotBeforeUpdate: Called before the component updates to fetch a snapshot before the update.<\/li>\n<\/ol>\n

      The order in which React lifecycle methods are called is as follows:<\/p>\n

        \n
      1. builder<\/li>\n
      2. obtainStateFromProps<\/li>\n
      3. interpret<\/li>\n
      4. initialize when the component is mounted<\/li>\n
      5. – Is it necessary to update the component?<\/li>\n
      6. capture the previous state before an update<\/li>\n
      7. Update after component render.<\/li>\n
      8. This refers to when the component is about to be removed from the DOM.<\/li>\n<\/ol>\n

        When using React, you can choose the appropriate lifecycle function based on the specific needs of the component to implement the corresponding logic.<\/p>\n","protected":false},"excerpt":{"rendered":"
