When doing concurrent programming in Go, it can be seen that the goroutine may not execute and the main thread stops before it finishes executing. This is a problem that frequently appears when doing concurrent programming. Waitgroups solves the problem in an easy way. How Golang waitgroups work? Waitgroup is a blocking mechanism that blocks […]

Golang select statement is like the switch statement, which is used for multiple channels operation. This statement blocks until any of the cases provided are ready. This post will explore the select statement in the Go programming language. Golang Select Statement Syntax The syntax of the select statement is like the switch statements. It is

In this post, we will see how to work with multiple goroutines. If you are looking for the basics, please go through Goroutines in Golang and Channels in Golang.
