Golang provides two types of timers: time.Timer and time.Ticker. Each have different use Case.
time.Timer is used to create a timer that fires once after the specified duration, while time.Ticker is used to create a timer that fires periodically at the specified interval.
Example 1: Timer
https://goplay.tools/snippet/tSGKq126doi
package main
import (
"fmt"
"time"
)
func main() {
timer := time.NewTimer(2 * time.Second)
go func() {
fmt.Println("Inside go routine. Sleeping for 10 seconds")
time.Sleep(10 * time.Second)
}()
<-timer.C
fmt.Println("Exited after two seconds")
}
Example 2: Ticker
https://goplay.tools/snippet/MiiE4p4fLjb
package main
import (
"time"
"fmt"
)
func main() {
ticker := time.NewTicker(1 * time.Second)
go func() {
for t := range ticker.C {
fmt.Println("Tick at", t)
}
}()
time.Sleep(5 * time.Second)
ticker.Stop()
fmt.Println("Ticker stopped")
}
