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.
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'sreturn
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.
