Lockdown Learning – Day #44– Waiting for Goroutines in GoLang (Music Only)

Continuing with our lockdown learning of Go language. Here’s a video on the Need to wait for goroutines in Golang

A goroutine may have to wait for another goroutine to complete. Using time.Sleep() is a very crude way to wait

package main

import (
	"fmt"
	"math/rand"
	"time"
)

func main() {
	go fixIssues()
	time.Sleep(time.Second * 5) //Unreliable.
	//So it would be good for the main goroutine to wait for fixIssues goroutine to complete
	//How do we do that? Next video 
	fmt.Println("***Enough! I am done waiting")
}

func fixIssues()  {
	i := 0
	rand.Seed(time.Now().UnixNano())
	iterations := rand.Intn(20)
	fmt.Println("Time required:", iterations, "seconds")
	for i < iterations {
		fmt.Println("Fixing Issues ...")
		time.Sleep(time.Second * 1)
		i++
	}
}
