JavaScript WeakRef Object Cache
A cache backed by WeakRef and FinalizationRegistry. Stored values are held weakly — the garbage collector can reclaim them if memory pressure is high, and the registry automatically cleans up stale entries from the internal map. Ideal for caching large objects (DOM nodes, rendered images) without causing memory leaks.
JavaScript Middleware Pipeline
A simple Koa/Express-style middleware runner for client-side use. Middleware functions receive a context object and a next() function — call next() to pass control to the next middleware or skip it to short-circuit the chain. Useful for building plugin systems, request pipelines, and composable validation logic.
JavaScript Worker Pool (Web Workers)
Manages a pool of Web Workers for CPU-intensive tasks (image processing, crypto, parsing). Distributes tasks across available workers using a round-robin strategy and returns a Promise per task. Falls back gracefully to inline execution in environments where workers are unavailable.
