Arrays are (almost?) directly mapped to JavaScript arrays in "prod
mode", while ArrayList wraps a JavaScript array, so arrays are a bit
lighter and faster (ArrayList methods are almost all inlined, but you
still have to pay for the creation of the wrapper, and of the Iterator
instances!)
I suspect this is negligible though, and you should really choose
depending on your needs, as those are different APIs for different
purposes.
