separated by ;)

What are Structs ?
 Collection of fields
 Similar concept to classes in Object oriented languages

What are structs ?
 Structs can also have functions just like classes.

Concurrency
 Go Lang provides the easiest way to create a new
thread.
 using the go construct before the function executes
the function in a new thread. These are referred to as
Go-Routines.

Channels
 Channels are the pipes that connect concurrent
goroutines. You can send values into channels from one
goroutine and receive those values into another
goroutine.

Channels
 We pass an 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 code can 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.
