FxTS is a functional programming library for TypeScript and JavaScript built on Iterable/AsyncIterable protocols. It provides lazy evaluation, composable pipe-based data transformation, and concurrency control for async operations with strong type inference.
Use cases
- process large or infinite sequences lazily without loading everything into memory
- compose map/filter/reduce pipelines with pipe and strong type inference
- control concurrency of async requests with backpressure
- write declarative functional code in TypeScript
- terminate async work early with take over AsyncIterables
When to choose
- you want lazy evaluation and AsyncIterable pipelines beyond what lodash or native iterator helpers offer
- you need curried, data-last function composition with excellent TypeScript inference
- you need to throttle concurrent async requests with backpressure
When to avoid
- you need a batteries-included utility belt with deep object manipulation like lodash
- your project cannot enable strict TypeScript compiler options
- you target environments without ES2018+ support and cannot use polyfills
