NAME¶
Array::filter - 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(isDiv@(3),ints);
// odds = [3,6];
}
Naturally,
all(p,filter(p,xs)) == any(p,xs)
