/**
 * `intersection(target, source)`
 *
 * Returns a new set containing only the values that exist in both the `target` set and the `source` set.
 *
 * ```ts
 * intersection(new Set([1, 2, 3]), new Set([2, 3, 4])); // Set([2, 3])
 * intersection(new Set([1, 2]), new Set([3, 4])); // Set([])
 * ```
 *
 * ```ts
 * pipe(new Set([1, 2, 3]), intersection(new Set([2, 3, 4]))); // Set([2, 3])
 * pipe(new Set([1, 2]), intersection(new Set([3, 4]))); // Set([])
 * ```
