Share this article

As is often the case in front-end development, it seems we have so much to learn and so little time to do it. I’ve rounded up another 20+ learning resources, interactive playgrounds, and other goodies for front-end learning.

So please enjoy the seventh installment of our Docs and Guides series and don’t forget to let me know of any others that I haven’t yet included.

1. Meteor: The Official Guide

This is a site from the official Meteor development team, outlining opinions on best-practice application development targeted at intermediate JavaScript developers who are already familiar with Meteor.

2. Gethtml

3. Learn ES2015

Maybe you’re like me and you’re tired of seeing so many ES6/ES2015 resources. Or maybe this is the one that you finally sit down with and it gets you over the hump of absorbing everything that’s new in the ECMAScript spec.

4. Flexbox Froggy

More from Nicolás Bevacqua, this time it’s a visualization playground to help you learn JavaScript’s new promises feature. What’s great about this is the ability to step through the visualized code components with the option to save the animated visualization as a GIF.

An interactive playground for learning CSS’s background-blend-mode and filter properties.
