I am making a website and I have a <textarea> where people can type text. I want to add a button that will undo the last thing they did in the textarea, if they typed a word, it should come back when they press the button.

I found something about document.execCommand('undo'), but I heard its not good to use anymore. Is there another way to do this with JavaScript?

Example:

• User types “Hello”.
• User deletes “ello”.
• I want to bring back the “ello” when they click the undo button.

Thanks!
