How do I clear all variables in node REPL?

Question

I open a REPL on my terminal with node or node -i.

After playing around, I’d like to clear everything in this REPL (chiefly the JS variables that I created). Is there a command to do that? I currently use .exit followed by node, but I’d like to do it without closing and reopening the REPL, and the .clear command does not seem to be working.

How about creating a new REPLServer instance?

$ node -r repl -e "repl.start()"
> const x = 'hello';
undefined
> .clear
Clearing context...
> x
Uncaught ReferenceError: x is not defined

REPLServer is customizable. See this reference: https://nodejs.org/api/repl.html .
