Array::filter(3) Filter a list according to a predicate.

SYNOPSIS

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

ARGUMENTS

p The predicate to test against

xs The array to filter

DESCRIPTION

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([email protected](3),ints);
     // odds = [3,6];
 }

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