Ticker & Tick

Ticker

Ticker -> untuk menampilkan waktu secara berulang.

type Ticker struct {
    C <-chan Time // The channel on which the ticks are delivered.
    r runtimeTimer
}

Ketika waktu ticker sudah expire, maka event akan dikirim ke dalam channel.

Ticker.Stop() -> Untuk menghentikan ticker.

package main

import (
	"fmt"
	"time"
)

func main() {
	ticker := time.NewTicker(1 * time.Second)
	fmt.Println(time.Now())
	for tick := range ticker.C {
		fmt.Println(tick)
	}
}

Tick

Kadang kita tidak butuh data Ticker nya, kita hanya butuh channel-nya saja -> pakai time.Tick(pause time)

package main

import (
	"fmt"
	"time"
)

func main() {
	ticker := time.Tick(1 * time.Second)
	fmt.Println(time.Now())
	for tick := range ticker {
		fmt.Println(tick)
	}
}
