core.async is a Clojure library that brings asynchronous programming and communication to both Clojure and ClojureScript, enabling developers to write concurrent code using channels, go blocks, and CSP-style constructs rather than callbacks or threads.

Features

  • go blocks for lightweight concurrent tasks that can pause and resume
  • Channels (chan) for communication between tasks
  • Parking operations for synchronous or blocking communication
  • Non-blocking alternatives
  • Thread pool management for behind-the-scenes task scheduling
  • A flow namespace providing a more structured flow abstraction (still evolving)
