You would use pipes to do this:

function myFunc(defaultDirection) {
    var someVariable = defaultDirection || false;

}

Not exactly - this does not let you set `defaultDirection` to `0`. – joews Jan 22 '15 at 12:21
good point! Never thought of that before actually – donnywals Jan 22 '15 at 12:22
