Node.js

  1. let i = 0
  3. const id = setInterval(callback, 1e3)
  5. function callback() {
  6.   console.log('called', i)
  8.   if (i === 3) {
  9.     clearInterval(id)
  10.   }
  12.   i++
  13. }

Output

  1. called 0
  2. called 1
  3. called 2
  4. called 3

  9.     fmt.Println("called", i)
  10. }
  12. func main() {
  13.     ticker := time.NewTicker(1 * time.Second)
  15.     i := 0
  16.     for range ticker.C {
  17.         callback(i)
  19.         if i == 3 {
  20.             ticker.Stop()
  21.             break
