Correct method to check jQuery has loaded

I have noticed a couple of methods to check whether jQuery has loaded, I'm curious to know if one is better than the other, or, more reliable?

In the past I have used this to check if jQuery exists:


But, here is another option, which checks to see if the object is defined:

typeof jQuery !== 'undefined'

Alternatively, is there an even better method than one of these two?

I don't think voters understood what I was asking. Honestly don't understand why this was downvoted...

Both of my original suggestions do work, but, can't find any performance stats to suggest one or the other.
