Small correction: The includes method *cannot* determine the existence of holes, since it doesn’t differentiate between holes and elements containing the undefined value.

['Foo',,'Bar'].includes(undefined) // true
['Foo',undefined,'Bar'].includes(undefined) // true

i find it strange that -5 ** 2 resolves to -25 instead of +25. any insight into why that decision was made?

great writing/reads. i've been enjoying them :)

Hey DChang,
It may be strange from the first look, but generally it's ok. The unary minus operator has less priority than the exponentiation operator.
Think of it as a math expression. It is expected 5**2 - 3**2 = 25 - 9 = 16, but not 5**2 - 3**2= 25 + 9 = 34.

Thanks! I'm glad you like the writings.
