In class components, which method is called right before a component is removed from the DOM?
- componentWillUnmount()
- componentDidUpdate()
- componentWillMount()
- componentWillUnmount()
In class components, the componentWillUnmount() method is called right before a component is removed from the DOM. This is the ideal place to perform cleanup tasks, such as removing event listeners or clearing timers, to prevent memory leaks or unexpected behavior after the component is unmounted. The other options are lifecycle methods, but they serve different purposes.
