Concurrency

Goroutines

Goroutine: a lightweight thread managed by the Go runtime.

It’s pretty simple to execute a function call as a new goroutine:

go f(param1, param2)

The program is terminated when the main goroutine finishes.

What?

• statically typed (w/ type inference)
• compiled (statically linked)
• memory safety, garbage collection
• built in dependency management
• concurrency:
  • goroutines (~coroutines/threads)
  • channels
  • select (for channels)
• interfaces for “virtual inheritance”, type embedding
• standardized formatting (gofmt)
• multiple implementations (gc, gccgo, gollvm, gopherjs, …)
