How to Use time.Sleep in Go

Use time.Sleep to pause the current goroutine for a specified duration without blocking other goroutines.

package main

import (
	"fmt"
	"time"
)

func main() {
	fmt.Println("Starting...")
	time.Sleep(2 * time.Second)
	fmt.Println("Resumed after 2 seconds")
}

For testing, use testing/synctest.Sleep to combine time.Sleep with testing/synctest.Wait for deterministic behavior.

time.Sleep pauses your program for a set amount of time, like waiting for a microwave to finish. It stops only the specific task running that line, letting other tasks continue working in the background. Use it when you need a simple delay between actions.
