Braces

Thanks to javascript, I think the age old argument BSD vs. K&R style curly braces is officially over. First, my own personal reason for using K&R. I just fixed a stupid error where I accidentally inserted a semi-colon at the end of one of my if statements. For example:

for (var i = 0; i < arr.length; i++)
{
    var foo = arr[i];
    if (!foo || bar.match(/regex/));
    {
        if (foo.baz)
        {
            arr.splice(i, 1);
            i--;
        }
        _fizz(bang(foo));
    }
}

It’s pretty hard to notice there, but it will definitely do some things you don’t expect. Doesn’t this look much more obvious?

if (!foo || bar.match(/regex/)); {

Look at that, you have a grumpy little guy ; { rather than the slightly unhappy );. Anyhow, the other reason to put the brace on the same line is to avoid a feature in javascript where it automatically inserts semi-colons for you:

return
{
   foo: 'bar',
   fizz: 'bang'
};

will return undefined instead of your object. I love it that avoiding a language feature comes around to justify my curly brace style choice.
