jQuery sizes by version and compression: https://mathiasbynens.be/demo/jquery-size

Wow compression ends up working really well for JQuery. Almost all the post-2.0 code size increases get totally absorbed.

I'm not surprised, JavaScript is compression-friendly. Usually minification brings the file size down by about a x3 ratio, and gzipping does the same.

What always impresses me with jQuery is the amount of features they're able to pack in 250 Mb of uncompressed code. They've got browser events, ajax and a crapload of selectors. Compatible with most browsers. Oh and performance is nice as well. Kudos to the jQuery developers!

I think it's 250 Kb rather than Mb.

I did a double take at that as well.

Imagine trying to maintain 250mb of JavaScript spaghetti!

This is the first time I can justify a move from a version 1.8.0 to 2.0 or 3.0 of a product with "it has fewer code".
