Useful JavaScript and jQuery Tools, Libraries, Plugins

Recently we’ve been receiving more requests for carefully selected, useful round-ups. We try to avoid round-ups on Smashing Magazine, but sometimes the format is useful and — if the resources are relevant — can be extremely helpful. Besides, we are glad to drive traffic to some obscure, yet useful resources and thus support the developers of these resources.

In this round-up, you’ll find some of the useful JavaScript and jQuery tools, libraries and plugins that we have stumbled upon recently. Hopefully, you’ll find them valuable for your upcoming projects. Among other things, you’ll find handy services and online utilities, recently released JavaScript libraries and jQuery plugins.
