	//Prototypal inhericance uses the the Object.create() syntax, remember this!!!!!

	let Human = {
	name: "David",
	create: function(value){

	instance[key] = value[key];

In a small town the population is p0 = 1000 at the beginning of a year. The population regularly increases by 2 percent per year and moreover 50 new inhabitants per year come to live in the town. How many years does the town need to see its population greater or equal to p = 1200 inhabitants?

	function nbYear(p0, percent, aug, p) {
	// your code
	let yearsGrown = 0;
	let popNow = p0;
	let amountGrown = ((popNow / 100) * percent) + 50;
	while(popNow < 1200){
	popNow += amountGrown;
	yearsGrown++;
	}
	console.log('population now ', popNow)

This was the free code camps Caesar's Cipher, hard but I did it, not sure why it doesn't work though

	function rot13(str) { // LBH QVQ VG!

	str = str.toUpperCase().split('');
	str.reduce(function(acc, item) {
	var patt = /[a-zA-Z]/g;

	if(patt.test(item)){
	item = item.charCodeAt(0);

	if(item > 77) {

	$scope.handle = "";

	$scope.lowerCaseFilter = function() {

aledwassell / Javascript I need to learn

Created December 31, 2016 03:26

This is the stuff I still have to get my head around in 2017

	ES6: The current version of JavaScript is ES2016 (aka ES7), but a lot of developers still haven’t properly learned ES6. It’s time to learn.

	Builtin methods: Learn methods for the standard data types (especially arrays, objects, strings, and numbers).

	Functions & pure functions: You probably think you’ve got a great grasp of functions, but JavaScript has some tricks up its sleeves, and you’ll need to learn about pure functions to get a handle on functional programming.
	Closures: Learn how JavaScript’s function scopes behave.
	Callbacks: A callback is a function used by another function to signal when there is a result ready. You say, “do your job, call me when it’s done.”
	Promises: A promise is a way to deal with future values. When a function returns a promise, you can attach callbacks using the .then() method to run after the promise resolves. The resolved value is passed into your callback function, e.g., doSomething().then(value => console.log(value));
