## What it is
Microjob is a tiny TypeScript library that wraps Node.js worker_threads into a simple promise-based API for running CPU-bound work in background threads. It manages a worker pool with auto self-healing and supports both sync and async anonymous functions as jobs.

## Use cases
- run heavy CPU computations off the Node.js event loop
- execute anonymous functions in worker threads
- parallelize CPU-bound tasks with a worker pool
- avoid blocking the main thread during intensive loops
- offload data crunching in a Node.js backend

## When to choose
- you need simple, promise-based multithreading for CPU-bound work in Node.js
- you want a worker pool without managing worker_threads manually
- your jobs are short-lived anonymous functions

## When to avoid
- your workload is I/O-bound rather than CPU-bound
- you need long-lived threads or shared state between workers
- you need to pass complex runtime context or non-serializable data to jobs
- you need a library with frequent updates or broad Node.js version support beyond 12+
