**Workit** is a lightweight Node.js library that provides a thread‑pool‑style abstraction using child processes. It lets developers define worker functions or Worker‑API classes, then manage a pool of forked processes with simple `send` and `invoke` calls, handling job queuing, life‑cycle, and two‑way communication—ideal for anyone needing easy parallel processing in JavaScript without dealing with low‑level child‑process code.
