Buffered Channels

Explore buffered channels in Go to understand how they help avoid deadlocks by allowing send operations without immediate receives, up to their capacity. Learn to create and use buffered channels to handle synchronization challenges in concurrent applications effectively.

We'll cover the following...

If you were able to understand the previous lesson, you should be more clear on the code provided in the lesson on deadlocks.

Go (1.6.2)
package main
import "fmt"
func main() {
	mychannel := make(chan int)
	mychannel <- 10
	fmt.Println(<-mychannel)
}

Now you’ll be fully clear on why the above code didn’t work. This is because of the sending and receiving operations which are blocking the code. When we wrap one of them in a goroutine such that they are ready to unblock each other, the program executes ...
