I Hate Clever Javascript Programmers [modified]

There is nothing clever here; the code was obfuscated with a tool; it was intended to be hard to understand; the original code is probably very readable.

I'm trying to decipher the inner workings of ShadowBox (a lightbox variant), and I found this (except when I found it, it was all on one line of code:
return (aW == null) ? a0 === "!=" : a0 === "="
? a2 === aX : a0 === "*="
? a2.indexOf(aX) >= 0 : a0 === "~="
? (" " + a2 + " ").indexOf(aX) >= 0 : !aX
? a2 && aW !== false : a0 === "!="
? a2 !== aX : a0 === "^="
? a2.indexOf(aX) === 0 : a0 === "$="
? a2.substr(a2.length - aX.length) === aX : a0 === "|="
? a2 === aX || a2.substr(0, aX.length + 1) === aX + "-" : false;Before anyone else mentions it, I *know* what a ternary comparison is and I use them all the time (and was doing so before many of you were even born), but I don't nest them like this. THAT is the shameful nature of the code. So, please stop trying to educate me as to the ways of the force.

As others have said there is nothing demented or intentionally spiteful about this at all. They simply used an optimization tool (minifier), which removes all white space and uses the minimum amount of characters for variables. It compresses JavaScript quite a bit for downloading. It is a highly common, and very recommended, practice. The actual source code with all comments and descriptive variable names is on the project site.

If you work your head around inline IFs you'll find them really useful. I use them in C# all the time!!
I agree -- they help promote a nice functional style. But this example is over the top.

I'm not saying I don't understand this code. I'm saying this code is ridiculous. And it's called a ternary comparison, not "nested if's".

Anytime I see variables like a0, a1, a2 etc. it's probably because the code has been run through a compression or obfuscation utility to make it smaller and less likely to be swiped. I'm guessing that's what's happened here. [edit: and if I'd read the responses so far I'd have seen that my reply was redundant]. Cheers, Drew.

Yes. my master. :suss:
I'd blame it on the Brain farts.. But let's be honest, it really is more like a Methane factory between my ears some days then it is anything else...

I 100% agree with you. Good code is readable. Code that is difficult to read leaves space for difficulty to find bugs which cost the company money. Maybee its a form of insecurity these guys have. E.g. If I make my code impossible to read, they'll have to keep me employed.
