console.log(Array.from(evens).sort()) // [2, 4, 6]
console.log(HashSet.size(evens)) // 3

Signature

declare const filter: { <V, U extends V>(refinement: Refinement<NoInfer<V>, U>): (self: HashSet<V>) => HashSet<U>; <V>(predicate: Predicate<NoInfer<V>>): (self: HashSet<V>) => HashSet<V>; <V, U extends V>(self: HashSet<V>, refinement: Refinement<V, U>): HashSet<U>; <V>(self: HashSet<V>, predicate: Predicate<V>): HashSet<V>; }
