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.
