I have a question about opening a window in the terminal but leaving no trace of it.

Hi everyone!

I have this question and I know no better place to ask it. So sorry if it's not that much related to the gui.cs in particular. My question is that I know that cleaning up the terminal with something like the clean command only pushes a few empty lines into the feed and moves the previous text up. But there are things like MC, Nano, VI ..., etc. that almost open a new window inside of the terminal and on exiting restore the previous state without leaving a trace:

How do you do this? What should I search for? What is the name of this trick/feature/... ? I don't want to do this in C#, I want to implement a JavaScript node app that does that so I want to know how it is done.
