Promise Fun

Promise Fun is a curated reference collection centered on JavaScript promises, asynchronous patterns, and related utility packages. It serves as an index to numerous focused modules created for common promise-based programming tasks. The collection includes tools for concurrency control, mapping, queues, retries, delays, timeouts, debouncing, throttling, filtering, and asynchronous iteration. Its documentation also explains practical patterns for solving recurring asynchronous programming problems. One example shows why promise-returning functions must be created lazily when limiting concurrency instead of constructing all promises in advance. The repository functions primarily as an educational directory rather than a standalone runtime library. It helps developers discover small specialized packages instead of building every asynchronous control mechanism themselves.
