loops golang code example

Example 1: go for loop

package main

import "fmt"

func main() {
	sum := 0
	for i := 0; i < 10; i++ {
		sum += i
	}
	fmt.Println(sum)
}

Example 2: golang loop

package main

import "fmt"

func main() {
	sum := 0
	for i := 0; i < 10; i++ {
		sum += i
	}
	fmt.Println(sum)
}

Example 3: go loops

// There's only `for`, no `while`, no `until`
    for i := 1; i < 10; i++ {
    }
    for ; i < 10;  { // while - loop
    }
    for i < 10  { // you can omit semicolons if there is only a condition
    }
    for { // you can omit the condition ~ while (true)
    }
    
    // use break/continue on current loop
    // use break/continue with label on outer loop
here:
    for i := 0; i < 2; i++ {
        for j := i + 1; j < 3; j++ {
            if i == 0 {
                continue here
            }
            fmt.Println(j)
            if j == 2 {
                break
            }
        }
    }

there:
    for i := 0; i < 2; i++ {
        for j := i + 1; j < 3; j++ {
            if j == 1 {
                continue
            }
            fmt.Println(j)
            if j == 2 {
                break there
            }
        }
    }
