Web site "developers" ... who can't.
Java clue?
Possibly repeating a rant of old
It's incredible how much sites are relying using Javascript to get your browser to do their work these days. It's astounding the sheer quantity of this crap your machine is having to process just to assemble what should be a simple web page, for things like Facebook, Google, YouTube; in fact pretty much every major site around these days. But what is truly shocking is just how much of it is appallingly broken code. I'm sitting watching the errors (that users do not normally see) streaming up the console as I simply reload a Facebook page, watch a YouTube video, or post a Tweet.
[Warning: nerdy bit.] I'm not just seeing simple unimportant unassigned values. These are user functions which return inconsistent values and cause errors to be thrown. Or clear syntactic errors which the interpreter is doing it's best to second-guess and correct. By the look of it, these days even run-testing your own code is considered a step too far and the words "Quality Assurance" don't belong in polite society.
Case in point (and this is just a tiny fragment from one Facebook page update):

If you ever wondered why some pages seem to take a glacial age to finish loading, or some just get terminally stuck, odds are it's the fault of some crap second-rate programming by a clueless monkey. It looks like some of these "developers" couldn't even complete a newbie's assignment. I don't write JavaScript, as a rule, and even I could fix some of this shit.
