Splits values into two groups according to a predicate function, which specifies which group an element in the input collection belongs to. If the predicate function returns a truthy value, the collection element belongs to the first group; otherwise, it belongs to the second group.
Use Array.prototype.reduce()
and Array.prototype.push()
to add elements to groups, based on the value returned by fn
for each element.
