Thanks for the video, I'm just now seeing the beauty in goroutines

Hey Could we call wg.Add(1) before go routine, in rear scenario there might chances to miss wg.Add() after goroutine spawn.

@abhinavkumar3751 6 ай бұрын

Yeah we can do that, if you know you're going to have exactly 100 threads, then you can do wg.Add(100) at start.

wg is a pointer variable but neither asterisk (*) nor (&) is being used, why ?

@dhanushs1802 2 жыл бұрын

we are making a copy of sync.WaitGroup by taking advantage of zero value in golang here. And we are not assigning anything to wg here after declaring it. We are just calling the relevant methods on it. So we don't have a need of pointers here isn't it.

Why did you remove my comment about the wg.Add(1) being in the wrong place? My Go did not accept that, so I wanted to help out.

I didn’t removed anything, your comments are landing in spam

Curious, where do you think is the right place to add? And why?

what if we are not concernerd with result of go routine, do we still need to use wait?

@SagarKumar-yr4ky Жыл бұрын

Same question, let's say we fire multiple go routines in a for loop & we just want them to process something or do some CRUD operation in DB and we don't care about the result of the method called by these go routines, do we still need wait groups in that case too? I mean, CRUD operation will be executed in the background anyways right ?

@@SagarKumar-yr4ky yes you will need wait groups in these scenarios too. Basically whenever you want all your go routines executions to be done/finish properly you have to use wait group. If you don't use wait group then the main process execution may end before the complete execution of go routine, so to keep the main process to wait for these go routines to complete their process we need to add wait group.
