As I type into a regular textarea on this site I'm wondering where these textarea replacements on websites are? I'd love for a few examples of this happening. "Many" JS programmers recreate the textarea? Show me.

It depends exactly what you mean by textarea. If you need rich text you need something custom. (Although you can use contenteditable as a base)

There are sites like GitHub that slightly enhance a regular textarea (IIRC it is a textarea, haven't thought about it too much)
