## What it is
A curated collection of sindresorhus's promise utility modules, promise patterns, and tutorials for JavaScript. It serves as an index to packages like p-map, p-limit, p-retry, and delay for async control flow.

## Use cases
- find a javascript library to limit promise concurrency
- retry async functions with backoff
- learn common async/await patterns
- promisify callback-style functions
- debounce or throttle async functions
- run promises in series or with timeouts

## When to choose
- you need a small focused promise utility for Node.js or browser JavaScript
- you want curated resources on promise patterns and async problems

## When to avoid
- you need a full-featured batteries-included async framework
- you work in a non-JavaScript language

- maturity: active
- function: concurrency, developer-tools
- domain: developer-tools, awesome-lists, programming-languages
