Answer 1

If you run repl from a file:

// repl.js
const repl = require('repl');
repl.start();

then you can use.clear

node repl.js
> var a = 5;
undefined
> a
5
> .clear
Clearing context...
> a
ReferenceError: a is not defined

The first google link leads to an example of clearing the node console: https://gist.github.com/KenanSulayman/4990953
or
process.stdout.write('\033c');
