Learning Functional Programming in Go

Using homebrew to install Go

On a Mac, we can use homebrew to install and manage our Go installations:

brew search go

Running the preceding command might return result like this: go go@1.4 go@1.5 go@1.6 go@1.7 go@1.8 The checks indicate which versions of Go are already installed. To install go version 1.5, we can run brew install go@1.5. To install the latest version of go (currently 1.9), run  brew install go.
