Example:

import { minOf } from "https://deno.land/std@0.116.0/collections/mod.ts"
import { assertEquals } from "https://deno.land/std@0.116.0/testing/asserts.ts"

const inventory = [
     { name: "mustard", count: 2 },
     { name: "soy", count: 4 },
     { name: "tomato", count: 32 },
];
const minCount = minOf(inventory, (i) => i.count);

assertEquals(minCount, 2);
