11 months ago Maybe it was updated in the meantime, but essentially it describes it as vec1.x*vec2.x + vec1.y*vec2.y which is the same definition as I've seen pretty much everywhere else, too.
(What could at first glance confuse here is naming two vectors x and y ... =)

The definition of the dot product is not one I'm familiar with. Am I getting confused here? Happy to submit a pr if this is indeed a mistake!
