Installing Node.js with `nvm` to Linux & macOS & WSL

A quick guide on how to setup Node.js development environment.

	Cloning into 'my-awesome-proj'...
	ssh: connect to host github.com port 22: Connection timed out
	fatal: Could not read from remote repository.

	$ # This should also timeout
	$ ssh -T [email protected]
	ssh: connect to host github.com port 22: Connection timed out

	$ # but this might work

	path "sys/leases/*"
	{
	capabilities = ["create", "read", "update", "delete", "list", "sudo"]
	}

	# Manage auth methods broadly across Vault
	path "auth/*"
	{
	capabilities = ["create", "read", "update", "delete", "list", "sudo"]

	// src/middlewares/flatten-response.js
	function flattenArray(obj) {
	return obj.map(e => flatten(e));
	}

	function flattenData(obj) {
	return flatten(obj.data);
	}

	function flattenAttrs(obj) {

	const minute = 60;
	const hour = minute * 60;
	const day = hour * 24;
	const week = day * 7;
	const month = day * 30;
	const year = day * 365;
