Concurrency in Golang

• Concurrency in A Tour of Go
  • go routines are kind of like fancy queues designed for concurrency
  • select is kind of like a switch statement for channels
  • (<-) = "the channel operator"
    • when left operand is a channel, read ch <- data as "sending" data to the channel ch
    • when right operand is a channel, read data := <- ch as "receiving" from the channel ch and assigning to data
      • when left operand is missing, then we are "receiving" without assignment e.g. when passing the result directly to another function

  • func pong(pings <-chan string, pongs chan<- string)
  • <-chan string means a channel that can only receive
  • chan<- string means a channel that can only send
