[node.js] How to create full path with node's fs.mkdirSync?

fs-extra adds file system methods that aren't included in the native fs module. It is a drop in replacement for fs.

Install fs-extra

$ npm install --save fs-extra

const fs = require("fs-extra");
// Make sure the output directory is there.
fs.ensureDirSync(newDest);

There are sync and async options.
