Implement while loop in Go (Golang) - Welcome To Golang By Example

Go doesn’t have the while keyword. Instead, it has the for keyword only. However for keyword can be used to simulate the functionality the same as while.

for loop in GO basically has three parts:

for initialization_part; condition_part; increment_part {
   ...
}

for loop can be implemented to behave the same as while if initialization_part and increment_part can be skipped. Here is an example:

package main

import "fmt"

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

Output:
