React Lifecycle Methods Execution Order
The order of execution in the React lifecycle is as follows:
- Initialization phase (Mounting): The component is created and inserted into the DOM.
- create a constructor
- function that returns the updated state based on the changes in props.
- create()
- The component has mounted.
- During the updating phase, a change in the props or state of a component results in a re-render.
- static method that fetches data from props and returns a new state
- Is it necessary to update the component?
- display()
- retrieve a snapshot before updating()
- This method is called after a component has been updated.
- Unmounting: Removing components from the DOM.
- When the component unmounts.
- Error handling phase: errors occurring during component rendering.
- A method called getDerivedStateFromError that is static.
- Handle errors in the component.
