built to normalize features in browsers (read: usually normalizing between IE and other browsers). This is why code sent down to a user browsing with Firefox or Chrome will get references to nonstandard IE methods such as attachEvent (even if that code will never run, thus why these branches of code are dead weight). And that’s why users of jQuery Mobile browsing on iOS and Android will get the same references, because jQuery Mobile rests on top of jQuery. But what a waste of bandwidth, which is especially noticeable in the case of mobile devices and networks!
There are ways around this. Fortunately, some libraries such as YUI will perform feature tests and only load things that need to be sent down the wire (for example, a browser with native JSON support won’t get blindly sent a JSON polyfill that will never get executed). Some folks write special hacks in their code that make browser-specific branches, but end up being unnatural or unwieldy to maintain (Rebecca Murphey mentions the problem of maintaining this sort of code in one of her recent posts).
And then along came Joe Hewitt’s hascan, to little fanfare unfortunately. Hascan uses has.js, Node, and Browserscope to produce tailor-made versions of code delivered to browsers with only the code they need! A little controversial is the use of user agent sniffing, which has seemed to overshadow how awesome this tool really is (see the comments on FunctionSource’s article for more details). Don’t let the user agent sniffing scare you – I believe hascan is worth a serious look and I hope its general approach to eliminating “dead code” will catch on and gain more support.
jsfx
jsfx (by Egon Elbre) is a JavaScript sound effect generator that can dynamically create a whole range of sounds. It’s not exactly new, but it’s made the rounds a bit on Twitter this week, so it’s worth a mention! Since it’s been around a little bit, some folks have made stuff using it, including a drum sequencer and some crazy trippy audiovisual thing that seems to be like an animated technicolor Zen rock garden with the NBC chime as the soundtrack. Or something. Yeah. Oh yeah, if you just want to play around with jsfx itself, load up the handy demo and just click “Randomize” to your heart’s content. You’ll be surprised at the amount of diverse sounds you can get out if it.
html2canvas
html2canvas (by Niklas von Hertzen) is a mad scientist’s attempt at capturing a “screenshot” of webpages in canvas. Ok, Niklas isn’t a mad scientist, but in my mind he might as well be. Html2canvas doesn’t actually take a screenshot, but rather goes through the DOM element by element, inspecting computed styles added to each element, and attempts to translate that to Canvas. It does it amazingly well, as the examples show in their A-B comparisons.
