JavaScript braces on new line or not? [closed]

Answer 1

All subjective. Some are slightly better but the difference is negligible. The most important thing to do is stay consistent across all your code.

Personally, I prefer the tucked in style, with 4 space 'real' tabs.

function a() {
    if (b) {
        do;
    } else {
        do2;
    }
}

Answer 2

I prefer them on the same line, but mostly because I pass anonymous functions as arguments a lot...it saves some space and makes the function definition look less jarring. Of course, this is just an opinion, and I agree with Bytecode Ninja that consistency is the most important thing.

Answer 3

This is a Holy War to which you will never get a usable answer! Just stick with whatever everyone else in the project is using and don't argue!

For what it's worth, I'm a K&Rite. I find the OTBS puts a lot of visual space between an opening structure and the following statement, when those two lines are often strongly related so would be better presented together, without an intervening almost-blank line. I like to keep my blank lines reserved for separating blocks of related statements.

In a coding style which a lot of whitespace anyway, this may be relatively unimportant. But personally I value terseness, so I can keep more of the program on-screen.

I don't buy that having the open-brace on a different column to the close-brace is an issue. It's still easy to see the block shape just from the indents. Unless you're using hanging indents. Don't do that. But that's another Holy War entirely.
