The document outlines the four parts of a React component's lifecycle: mounting, updating, unmounting, and error handling. It describes the order of lifecycle method calls during mounting (constructor, render, componentDidMount), updating (getDerivedStateFromProps, shouldComponentUpdate, render, componentDidUpdate), and unmounting (componentWillUnmount). It also lists the error handling methods (getDerivedStateFromError, componentDidCatch) that are called when errors occur.

2. Component’s lifecycle
• A component’s lifecycle can be divided into 4
parts:
• Mounting— an instance of a component is being
created and inserted into the DOM.
• Updating — when the React component is born in
the browser and grows by receiving new updates.
• Unmounting—the component is not needed and
gets unmounted.
• Error handling—called when there is an error
during rendering, in a lifecycle method, or in the
constructor of any child component.

3. Mounting
• These methods are called in the following
order when an instance of a component is
being created and inserted into the DOM:
• constructor()
• static getDerivedStateFromProps()
• render()
• componentDidMount()

4. Updating
• An update can be caused by changes to props
or state. These methods are called in the
following order when a component is re-
rendered:
• static getDerivedStateFromProps()
• shouldComponentUpdate()
• render()
• getSnapshotBeforeUpdate()
• componentDidUpdate()

5. Unmounting
• This method is called when a component is
removed from the DOM:
• componentWillUnmount()

6. Error Handling
• These methods are called when there is an
error during rendering, in a lifecycle method, or
in the constructor of any child component.
• static getDerivedStateFromError()
• componentDidCatch()
