Go (also known as Golang) is one of the most popular languages today and is a key part of many enterprise tech stacks. Because Go's memory management architecture makes concurrency easier, many developers prefer it over traditional languages.

In this course, you will learn the core constructs and techniques of Go as well as advanced concepts of the language. In particular, you’ll learn how to program efficiently by becoming aware of the pitfalls and patterns that are commonly encountered in Go and by building your own applications.

Once you’ve completed this course, you will be able to write concurrent programs and improve the performance of existing ones, thus creating a more robust experience for everyone. Concurrency is in high demand today since it enables developers to reduce execution time of applications significantly, and Golang provides a very rich support for achieving this.

Concurrency in Go

## Bidirectional nature of the channel

Channels are bidirectional. That is, we can both send and receive data using channels. Let’s look at the working code for a bidirectional channel.
the bidirectional channel:

package main
import "fmt"

func printValue(goChannel chan int) {
	fmt.Println("Value inside the channel is ", <-goChannel)
	goChannel <- 1
}

func main() {
	goChannel := make(chan int)
	go printValue(goChannel)
	goChannel <- 2
	fmt.Println("Value inside the channel is ", <-goChannel)
}

We can send to and receive from the `printValue` function in the code.

## Unidirectional nature of the channel

In programs, we often only send values to or receive values from a function. If we don’t want a bidirectional channel, we can mention it in the function definition.


### Receive-only channel

The receive-only unidirectional channel is declared as follows:


```go
receiveOnly := make(<-chan int)
```

Let’s look at the working code for the unidirectional channel that receives the data.
