Array.filter (3kaya)

[a] filter( Bool(a) p, [a] xs )

p The predicate to test against

xs The array to filter

Each element of xs is tested against the predicate p

The returned list contains those elements of xs for which the predicate is true. The predicate function may of course be partially applied for ease of programming.

• Bool isDiv(Int d,Int a) {

       return (a%d==0);
  

  }

  Void main() {

       ints = [1,2,3,4,5,6,7,8];
       odds = filter(isDiv@(3),ints);
       // odds = [3,6];
  

  }

Naturally, all(p,filter(p,xs)) == any(p,xs)
