Notepad

I made the switch to a Mac from PC a short time ago.

When i was using a PC, Windows had the Notepad app that enabled me to quickly type text into it and save it, or paste into it.

Does Mac have something equivalent? I find myself having to wait until Pages fires up before I can paste something quickly or type something quickly. Is there a lightweigh app like Notepad that Mac has?

Thank-you for your time and expertise!
