I don't know about Javascript, but a good deal depends on how that functionality is implemented, and what language you're in. They're not always the same thing, and shouldn't always be used like they are the same thing. Again though, they may be in Javascript, i'm not saying they're not. (I'm not really a javascript expert)
In the Java language, for example, you have the instanceof operator. This
is fine if you only need to check the type of something only a few times,
but if it's a several times per unit time kinda thing, you start to run
into efficiency problems. So using methods that make use of more efficient
algorithms become the better way to go.

It doesn't make any difference save for a few characters.
