"Only one level of indentation per method". This image just made my day :)

Wow. This is coded badly

I'm ashamed to say some of my quick and dirty scripts look similar. Usually clean them up into multiple functions in a separate file when I can.

@tisaconundrum At least it's better than a single if that is long 1000 characters and chained with ands...

One level of indentation is a good rule of thumb, but not always achievable. especially in JS.

It looks like multiple users can share the same e-mail address. ^^

@Greggergalactic
In the case of Promises -- and especially serial Promise trees -- this is extremely difficult to do.

CoffeeScript:

function = (args) ->
externalPromiseService(args)
.then (resolve_value) ->
# code (interior)
, (err) ->
# catch

That's three levels of indenting before getting to your code. You can offload the interior to another method, but you've still exceeded the rule-of-thumb by two levels. Serial Promises require three levels of boilerplate, and breaking those levels out decreases their readability.

@Greggergalactic
Yeah, I totally agree. 🙁

Nesting, nesting, nesting.

If you turn it to the left
it kind of looks like the iron
throne.

@Codebeard true :)

@andros705 they're actually quite useful. But if you want to yell at JavaScript for supporting them, you should include a few others in your tirade: Ruby, Lisp, Python, Haskell, C++/C#, Java, Go, Lua, Perl, PHP, R, Rust, Scala ...
