There is still the issue of potential libraries that produce
arraylikes that don't inherit from a built-in arraylike prototype:
those won't benefit from your polyfill without changing their
inheritance strategy.
I don't understand the expression

This seems overcomplicated. Isn't the likelier code something like

ib.length; i++) a.push(b[i]); return a; });
Isn't the whole point to impute arraylikeness to the parameter?

Hi,
I was reading the current spec for Array.from and it felt too
complicated to me. Currently, at a high-level it reads like:
1) if the argument is iterable (@@iterable symbol), create a fresh array
made of the values iterated on with the iterator
2) (step9) if the object is array-like, len =

I've been following the specification of Array.from very closely since the
day Dave and I first designed it and it's exactly as
16 matches
