So, I'm looking into something and end up on Stack Overflow. Someone posted the question:

"Does minified javascript improve performance?"

This question was old as shit, all they way from 07/25/09, and about an Adobe Air application. (Remember that? Me neither...) It had a great, accepted, and still accurate answer, posted the same day the question was asked. Now, fast forward 8 years and on 12/08/17 (A mere 7 months ago...) the following answer was posted. I don't know what they were thinking, but here it is, complete and unabridged, with my comments in square brackets:

"I'd like to post this as a separate answer as it somewhat contrasts the accepted one: [Somewhat contrasts? More like completely contradicts...]

Yes, it does make a performance difference as it reduces parsing time - and that's often the critical thing. For me, it was even just simply linear in the size and I could get it from 12s to 4s parse time by minifying from 3MB to 1MB. [First off, your parse time should NEVER be THE critical thing, but secondly, and more importantly, WHO THE FUCK HAS 1MB OF MINIFIED JS ON A PAGE!!!]

It's not a big app either, it just has a couple of reasonable dependencies. [THERE IS ABSOFUCKINGLUTELY NOTHING REASONABLE ABOUT ANYTHING HE JUST SAID! What dependancies is he using?! You could use minified and not even gzipped jQuery, AngularJS, Vue, Ember, React, AND Dojo libraries on the SAME PAGE, AND have 118k of application code, AND STILL NOT HAVE HIT 1MB QUITE YET!!!]

So the moral of the story here is: Yes, minifying is important for performance - and not because of bandwidth, but because of parsing. [Javascript should NEVER take longer to parse then to download, even on a low powered device...]"

So, yeah, I'm at a loss for what this guy was thinking, but the thought the people like this exist, and that my browser might one day be subjected to their horrific nightmare of code terrifies me...

    It has to be for a game or 3d application surely. The unreal engine compiles down to 25mb of asm.js min/gzip so could be a smaller library than it.

    @Wozza365 It's definitely possible, and I would be inclined to agree with you, if he hadn't said that it was an app and that it wasn't that big.

    I don't think anyone that's building a browser based game that's large by website standards would describe it as "not a big app" in anything other then a game development context.

    If you are making something like that, you KNOW that you are making a browser do things it was never meant to do and that it's going to be huge... lol
