How to listen to state changes?

Use a ref and measure the size of the container element
Use a setInterval() function
Use a window event listener
Use the componentDidUpdate() lifecycle method

In React, you can listen to state changes by using the "componentDidUpdate()" lifecycle method. This method is called after a component's state has been updated, and you can use it to perform additional actions or update the UI based on the new state. For example, you can use this method to update the DOM, call a web API, or trigger an animation.
