Solution in JavaScript warning: parseInt() is nutty!

	function solution(X, Y, D) {
	let range = (Y - X); // max distance to go
	// special cases
	let hops = D === Y ? 0 : parseInt(range / D); // whole jumps [1]
	let extra = range % D; // any left over hops required
	console.log(`===>\| X:${X} \| Y:${Y} \| D:${D} \| range:${range} \| hops:${hops} \| extra:${extra} \|`)
	return extra ? hops + 1 : hops

NeuTrix / How to start a new GitHub repo

Start a New Git Repo

	http://kbroman.org/github_tutorial/pages/init.html
	git/github guide
	Start a new git repository
	Your first instinct, when you start to do something new, should be git init. You’re starting to write a new paper, you’re writing a bit of code to do a computer simulation, you’re mucking around with some new data … anything: think git init.

	A new repo from scratch
	Say you’ve just got some data from a collaborator and are about to start exploring it.

	Create a directory to contain the project.
	Go into the new directory.
