In-memory cache utilities, such as memoization and caches with different expiration policies.

import { memoize, LruCache, type MemoizationCacheResult } from "@std/cache";
import { assertEquals } from "@std/assert";

const cache = new LruCache<string, MemoizationCacheResult<bigint>>(1000);

// fibonacci function, which is very slow for n > ~30 if not memoized
const fib = memoize((n: bigint): bigint => {
  return n <= 2n ? 1n : fib(n - 1n) + fib(n - 2n);
}, { cache });

assertEquals(fib(100n), 354224848179261915075n);
