JavaScript braces on new line or not? [closed]

Question

At work, we place braces on the next line, but at home, I do the opposite. Which one do you prefer? (K&R vs OTBS)

function something() {     // ... }  function something() {     // ... } 

A lot of JavaScript libraries seem to use the OTBS (one true brace style). I'd like to follow them for consistence among other JavaScript projects, but doesn't K&R style look more readable?

Note: We know the problem with return and braces in JavaScript, that will always be an exception. However, that is only a single case.

Answer 1

Douglas Crockford gives a reason for choosing the K&R style¹:

I always use the K&R style, putting the { at the end of a line instead of the front, because it avoids a horrible design blunder in JavaScript's return statement.

The blunder he is referring to is how JavaScript handles the return statement differently in the following two scenarios:

return {    'status': 'ok' }; 

... and:

return  {    'status': 'ok' }; 

The first one will return an object with a status property, while the latter will return undefined because of semicolon insertion.
