trie‑memoize is a tiny JavaScript library that provides a memoization helper where each argument of the wrapped function becomes a separate level in a cache‑trie (using plain objects, `Map` or `WeakMap` for each level). It offers O(n) look‑ups, works best for functions with a fixed number of arguments, and is aimed at developers who need fast, memory‑efficient caching for pure functions in Node or browser environments.
