Go: For

In Go we have only construct for looping which is For. Here we will discuss some basic uses of for -

For with single condition:

    i := 1
    for i <= 5 {
        fmt.Println(i)
        i = i + 1
    }

A classic for loop:

    for i := 1; i <= 9; i++ {
        fmt.Println(i)
    }

For loop without condition:

for without a condition will loop repeatedly until you break out of the loop or return from the enclosing function.

    // break
    for {
        fmt.Println("loop")
        break
    }
    //continue
    for n := 0; n <= 5; n++ {
        if n%2 == 0 {
            continue
        }
        fmt.Println(n)
    }
