It’s that time again to get learning! As before, I’ve collected a number of different learning resources, including guides, docs, and other useful websites to help you get up to speed in different areas of front-end development.

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

10. How available are the web platform’s features?

11. The State Of JavaScript Developer Survey

“Over nine thousand developers took part in the first edition of the State Of JavaScript survey. They answered questions on topics ranging from front-end frameworks and state management, to build tools and testing libraries. You’ll find out which libraries developers most want to learn next, and which have the highest satisfaction ratings. And hopefully, this data will help you make sense of the ever-changing JavaScript ecosystem.”
