JavaScript open brace in the same line

Question

I remember there is a convention/recommendation to put opening brace in the same line, because of the way JavaScript adds a semicolon or something.

//OK
fun         


        

Answer 1

There is no issue with declaring functions, but you can get into trouble when returning objects:

function foo()
{ // this is OK

    return
    { // this is BAD!
        name: "bletch"
    };
    // actually returns undefined!
}

A semi-colon is automatically inserted after the return statement, and that will break your code.
