Minimal async jobs utility library, with streams support
Runs iterator over provided array sequentially. Stores output in the `result` array on the matching positions. In unlikely event of an error from one of the jobs, will not proceed to the rest of the items in the list and return error along with salvaged data to the main callback function.
Node.js is an event-based server-side JavaScript engine.
