Undefined array

How would we use an undefined array as a crutch; that is, a size model for a whole series of arrays that might get generated to fit this profile?

 > a = new Array(10)
<- (10) [empty × 10]

How would Array.forEach() create another array with defined values given this array model?

Isn’t it abt that instance from Wanderlust?


That is an identity which makes sense to declare as a constant.
