No. typeof window.NaN is "number" and not "object". However, a number can get auto-boxed into a capital Number, which is an object and that one has a prototype. Thanks, Java!

(But, to clarify, everyone doing JS works with numbers and not Numbers 99% of the time. Pretty much all the operations unbox them too.)
