You know why i hate JavaScript?

Instead of writing

return x.y.z;

I wrote

return
x
.y
.z;

Just for making the code look clean
and everything broke...

I prefer the one-liner...but why are you returning 3 variables? In my Point of view thats not good practice

@oxmox ? Its a chain.. Its returning z from y from x.

To be honest this looks not clean to me. It looks like a waste of space.

This happens because it is possible to omit ; in Javascript. But in reality, statements should finish with ; and interpreter puts that semicolons itself, if it thinks that you forgot them.

That is the exact case happened to you. JS interpreter converts your code to :

function foobar(){
return;
x
.y
.z;
}

Which will of course return undefined.

return x
.y
.z;

Works.

Also,

return (
x
.y
.z;
);
Will work.

I don't like this approach of JS. Why is it not already mandatory using it, at least on strict mode ? Not using semicolons can always lead to break the code while minifying it.

@Artemix Piece of garbage indeed. Statements after return will not be ignored on the first pass :(

Good thing that it doesn't work since it wouldn't have been cleaner at all compared to keeping x and y on the same line and newlines for z and beyond

Essentially what you're saying is you don't like JS because it forces you to write cleaner code by accident

why not
return x.y
.t

@wombat that was just an illustration.. What I meant was the way it behaves is error prone...

go scala or Haskell and every is clean for you

Asking for errors then bashing the language for it, typical stupidity.
