Javascript brace style - THAT discussion probably again
-
So, I force myself to write Javascript with this brace style, since it seems that that's what is the "correct" style (example):
function ajaxError(data) {
alertBad(data);
}But then I see this [HTML5 WebSockets](https://www.tutorialspoint.com/html5/html5\_websocket.htm) and their example uses the style I'm used to in C#. So which is the "approved / standard / whatever" style? What style do you use: 1: Javascript style as per example? 2: Braces on separate lines style?

Use what pleases your eyes: you are the one looking at it ! I, personally (in all brace-using languages) would use a style similar to what you call javaScript, except I would put the closing brace aligned with the beginning of the block (i.e., under the 'f' in function. Similarly, under the 'i' in an if-block. My comfort zone for visual organization.

Same as you; mostly because I use the format document/selection menu option in Visual Studio to tidy up code and it's left at the defaults.

Yeah, I just tried that -- VS formatted it back to option 1. :doh: And it's such a useful feature with the html, I guess I'll have to either figure out if it's possible to tell the formatter to use C# style, or live with it, which I've pretty much gotten used to at this point anyways.

I agree with others that it's a matter of personal taste or it's defined by company's coding style / culture. Whatever the case is, I think the only important thing is to stay consistent. However, that example actually uses both styles so I don't think it's good idea to follow their styling...

I actually use both. Since they both have accepted styles I've adapted and just go with the flow.

Be careful! With JavaScript, it is not just a matter of style[^]. Just use the K&R style or you may introduce subtle bugs. Plus, K&R is the only true style :-D

I like you, refused to use 1TBS style braces (it's based on K&R and what JavaScript uses). I came from a C/C++ and PHP world after all. I was a real programmer. Besides, the style sucked. It's evil and ugly. Somewhere ponies will die if I used them. However, there is a valid reason why 1TBS became so popular with JavaScript. That code on the site was simply written by a rookie to JavaScript. Check out section 3 in the following link... Brace styles and JavaScript[^] That one little tidbit is the only valid reason for it and it started it all. In other words, it's only way to return an object literal like that in a function. So the community just adapted this style.

Yup - just read about that from Nemanja Trifunovic's post. That was a learning moment for me!

Oh snap, he beat me to it. It was a moment for me too man. Had it not been for that one point I'd not be using that style either. The only good news is at least you get used to it... at some point. :laugh:

The only language I know of that gives a crap is tcl. Fortunately I don't have to write it, I only have to parse it.

TOOTBS (aka K&R) is only about layout of statements. It gets confused with object literals purely because they use braces but for an entirely different purpose; same as '(' and ')' have multiple uses, as does the ','. That, combined with the lazy end of statement convention, is the only rationale for using TOOTBS. But you can use logical aligned braces even when returning objects either by making them subexpressions (using one of the alternative uses of '(' and ')') or by converting the object to a named object. Viz:
return (
{
p1: 1,
p2: 2
});
// or (my preference)
var result =
{
p1: 1,
p2: 2
};return result;

Using a variable is a given as a way to dance around it. As far as your first point it solves nothing and doesn't illustrate the point we're making. Try running it in regards to what we're talking about. In fact, here's a fiddle... Edit fiddle - JSFiddle[^]

Btw, when we say object literal in a return statement, that explicitly implies to not use a variable. Which is the entire point of what we're talking about. What is literal? Webopedia Definition[^]

Perhaps someone has mentioned this but haven't read *all* the responses :) There is actually a bit of a caveat with JS: it terminate some lines automatically (like an invisible semi-colon) Open your browser and go to the dev-tools (typically F12) and enter the following:
var f1 = function() {
return {
value: 'the-value'
};
}var f2 = function() {
return
{
value: 'the-value'
};
}Now have it execute
f1()
and then
f2()
. You'll quickly see the difference :) It is better to stick with the "standard" with braces on the same line. For my C# code it's is quite different.
