  Channels  Channels arethe pipes that connect concurrent goroutines. You can send values into channels from one goroutine and receive those values into another goroutine.
• 21.
  Channels  We passan object to channel by using <- operator on the right side. Similarly, using the <- operator on the left side of the channel will read off of it.

  Compilation/Deployment  Go codecan be compiled into binary code and does not need Go enviroment to run  Simply running “go install script.go” will create a binary file of the same name(without .go) extension in the GO_BIN directory.
