Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

JavaScript

Babel includes JSX processing.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

	INSTRUCTIONS: Block-scoping issues don't
	just crop up with if statements; you'll often
	see issues in for loops. Here's a classic
	example.
	
	Open your browser's console and click each
	of the buttons below. Notice how each
	button click outputs 3 instead of that
	button's number. Instead, clicking
	each button should log its number (e.g.
	clicking 'Button 0' should log 0 in the
	console). Let's solve it with ES6!
*/


var buttons = document.getElementsByTagName('button');

for(let i = 0; i < buttons.length; i++) {
	buttons[i].addEventListener('click', function() {
		console.log(i);

/*
	HINT: Think about the variable that is
	not changing. Could this be fixed by
	properly block-scoping it?
