filter¶

Filter something to an Arr (array) of values using predicate.

Instance of any type that has each(something, callback) implemented.

Decision function to be called with each item as first argument. When predicate(item) returns true, the item will appear in the resulting array.

Arr

(1...10).filter(F(num) num % 2 == 0)  # Gives [2,4,6,8,10]
(1...10).filter(X<5)  # Gives [1,2,3,4], predicate called as predicate(item, 5)
