Loops in Go ?

Why only For Loop?

In Golang, the only loop construct available is the for loop, and there are no other loop constructs like while or do-while that are available in other programming languages.

The reason for this is that the for loop is a general-purpose loop construct that can be used to implement any kind of looping behavior, including while and do-while loops.

For example, a while loop in other programming languages can be implemented in Golang as a for loop with a single condition expression:

// while loop in other languages
while condition {
    // do something
}

// equivalent for loop in Golang
for condition {
    // do something
}

Similarly, a do-while loop can be implemented in Golang as a for loop with a post-condition expression:

// do-while loop in other languages
do {
    // do something
} while condition;

// equivalent for loop in Golang
for {
    // do something
    if !condition {
        break
    }
}

As you can see, the for loop in Golang is very powerful and can be used to implement all kinds of looping behaviors, including while and do-while loops. By keeping the for loop as the only loop construct, Golang simplifies the language and makes it easier to learn and use, while still allowing for a wide range of looping behaviors.
