`buffered-async-iterable` is a small Node.js library that lets you process async iterables (including plain arrays and generators) in parallel with a configurable buffer size, optionally preserving order. It provides `bufferedAsyncMap` for parallel mapping and `mergeIterables` for merging multiple iterables, making it useful for developers who need efficient, concurrent handling of streamed or lazily‑produced data in JavaScript/TypeScript projects.
