Clear the terminal screen if possible
var clear = require('clear');
clear();Alternatively, you can use the clear cli.
$ clear
You can optionally give clear an argument of false to prevent it from clearing the screen.
This will not remove anything from the screen, but instead move your cursor to
position 0,0. Much like printing a \r instead of a \n to reset the current
line of output.
npm install [-g] clear
