It's a fallback in case parseInt returns NaN ("Not a number") for some
reason, so that you get a better value to work with (for example if some
follow-up code relies on that value being a number).
If the 0 is not reasonable either you could do something like this:
var newWidth = parseInt(oldWidth);
if (!isNaN(newWidth)) {
// process newWidth
}
