What is the code editor fCC uses in the browser?

What is the code editor that fCC uses? It’s been awhile since I’ve been on and the auto-input for what I’m typing is useful. Want to make sure that I can find/use a similar one when not coding in fCC. Is it called something?

Not entirely sure but looks a lot like codepen.io

the editor for the challenges? it is not created by FreeCodeCamp, but I can’t remember how it is called.
It is mentioned a few times in the forum…

It is the Monaco Editor.

The following npm packages are used.

If you want a local editor that works like the fCC editor then VS Code is a lot like it (based on the same editor component). It is also just the best one, in my opinion.
