As Moore’s Law is reaching the end of its lifecycle, the need for concurrency is rising and consequently, the need for a programming language that enables effective implementation of concurrent programs is rising too. For this reason, Go has become one of the most popular languages in recent times. This course aims to provide a detailed introduction to Go for beginners. Furthermore, it also articulates how Go is different from traditional programming languages that programmers are accustomed to in order to acquaint programmers getting ready to delve into Go with the language too.

An Introduction to Programming in Go

# Closing a channel
A sender can close a channel to indicate that no more values will be sent. Receivers can test whether a channel has been closed by assigning a second parameter to the receive expression: after


`ok` is false if there are no more values to receive and the channel is closed.

The loop `for i := range ch`  receives values from the channel repeatedly until it is closed.

>**Note:** Only the sender should close a channel, never the receiver. Sending on a closed channel will cause a panic.

>**Another note:** Channels aren't like files; you don't usually need to close them. Closing is only necessary when the receiver must be told there are no more values coming, such as to terminate a range loop.
