for

The for loop has three components, and can be used just like a for loop in C or Java. Go has no while loop because the for loop serves the same purpose when used with a single condition. Refer to the following example for more clarity:

package main

import (
   "fmt"
)

func main() {
   // Basic for loop
   for i := 0; i < 3; i++ {
      fmt.Println("i:", i)
   }

   // For used as a while loop
   n := 5
   for n < 10 {
      fmt.Println(n)
      n++
   }
}
