filter

Creates a new Set containing only the values for which the predicate returns true.

Available since v3.0.3

Import

import { filter } from '@helpers4/set';
// or, from the all-in-one package (same code, one install):
import { filter } from 'helpers4/set';

filter<T>(set: ReadonlySet<T>, predicate: function): Set<T>

Parameter	Type	Description
`set`	`ReadonlySet<T>`	The Set to filter
`predicate`	`function`	Function invoked with each value — return true to keep it

Set<T> — A new Set with only the matching values

Creates a new Set with only the values that satisfy the predicate.

filter(new Set([1, 2, 3, 4]), value => value % 2 === 0)
// => Set(2) { 2, 4 }

A helper named filter also exists in @helpers4/map. If you need both in the same file, rename at import with as:

import { filter as filter4set } from '@helpers4/set';
import { filter as filter4map } from '@helpers4/map';
