Quick Reference

Go Concurrency: Goroutines are cheap (2KB), spawn freely. Channels for communication, not shared memory. Close channels only from sender. Context for cancellation/timeouts. Worker pools for bounded concurrency. select for multiplexing. errgroup for error propagation. Always handle goroutine lifecycle. Test with -race flag.

Use When

  • Concurrent Go applications
  • Parallel data processing
  • Network servers
  • Background workers

Skip When

  • Simple sequential programs
  • Single-threaded requirements
  • CPU-bound without parallelism benefit
