It was more than two years ago now that I first published jQuery Fundamentals, a free online jQuery learning resource. Since then, the site has seen hundreds of thousands of visits — if you’ve learned jQuery in the last two years, chances are decent that you’ve landed on the page at least once or twice.
A lot happens in the world of front-end development in two years, including some big changes to the jQuery library — 1.4 was the current version when the site came out, and there have been four major jQuery releases since then. Those releases brought a slew of changes, including a complete rewrite of
$.ajax and friends, the introduction of deferreds and promises, new methods such as
.prop(), and a much more streamlined event binding API via
.on(). Slowly but surely, jQuery Fundamentals grew out of date.
More than a few people were puzzled that the original jQuery Fundamentals didn’t come with a price tag. I believed then that the content was more valuable if it was freely available than if it was locked behind a paywall or in a printed book, and since then, it’s been great to see it become a go-to resource for jQuery learning. Bocoup’s support of the overhaul and its commitment to the open web means that now, you can look forward to a much improved (and much more frequently updated) jQuery Fundamentals, with a price tag still set firmly at $0. We hope you like it.
