    new FilterPlugin()
]);
 
$results = $collection->filter(fn(int $x) => $x % 2 === 0);
// -> [2, 4]

MapPlugin

$collection = new TypedCollection('int', [1, 2, 3, 4, 5], [
    new MapPlugin()
]);

$results = $collection->map(fn(int $x) => $x * 2);
// -> [2, 4, 6, 8, 10]

ReducePlugin

$collection = new TypedCollection('int', [1, 2, 3, 4, 5], [
    new ReducePlugin()

$results = $collection->reduce(fn(int $carry, int $x) => $carry + $x, 0);
