node.js stdout clearline() and cursorTo() functions

Question

From a node.js tutorial, I see those two process.stdout functions :

process.stdout.clearLine();
process.stdout.cursorTo(0);

But I\'m using

Answer 1

This is the solution :

First, require readline :

var readline = require('readline');

Then, use cursorTo like this :

function writeWaitingPercent(p) {
    //readline.clearLine(process.stdout);
    readline.cursorTo(process.stdout, 0);
    process.stdout.write(`waiting ... ${p}%`);
}

I've commented clearLine, since it's useless in my case (cursorTo move back the cursor to the start)
