Pure functions for common tasks related to collection types like arrays and objects

Pure functions for common tasks around collection types like arrays and objects.

Inspired by Kotlin's Collections package and Lodash.

import { intersect, sample, pick } from "@std/collections";
import { assertEquals, assertArrayIncludes } from "@std/assert";

const lisaInterests = ["Cooking", "Music", "Hiking"];
const kimInterests = ["Music", "Tennis", "Cooking"];

assertEquals(intersect(lisaInterests, kimInterests), ["Cooking", "Music"]);

assertArrayIncludes(lisaInterests, [sample(lisaInterests)]);

const cat = { name: "Lulu", age: 3, breed: "Ragdoll" };

assertEquals(pick(cat, ["name", "breed"]), { name: "Lulu", breed: "Ragdoll"});
