asynquence is a small JavaScript library providing promise-style async sequence flow control, built as an abstraction on top of promise chains. It supports expressing async steps with callbacks, promises, generators, observables, and CSP-style coroutine concurrency via contrib plugins.

Use cases

• chain multiple async tasks in sequence without callback hell
• run async steps using generators or async/await
• coordinate parallel async tasks with gates and races
• emulate go-style CSP goroutines with generator coroutines
• handle event-reactive streams with observable-style sequences
• iterate over lists with async batch processing

When to choose

• you want a lightweight, dependency-free async flow-control abstraction over promises
• you need mixed paradigms (callbacks, promises, generators, CSP) in one API
• you're following You Don't Know JS async patterns and want the companion library

When to avoid

• you only need native promises or async/await with no extra abstractions
• you want a actively developed library with recent releases
• you need a full reactive streams implementation like RxJS
