Is the main function runs as a goroutine?

Question

Is the main() function runs as a goroutine? For example, I\'ve seen a crash stack trace like the below, which makes me ask:

goroutine 1 [running         


        

Answer 1

Is the main function a goroutine?

No.

The main function is a function.

In contrast,

A goroutine is a lightweight thread of execution. (source).

So goroutines execute functions, but goroutines are not functions, and there is not a 1-to-1 relationship between goroutines and functions.

However...

The main() function is executed in the first (and at startup, only) goroutine, goroutine #1.

But as soon as that function calls another function, then the main goroutine is no longer executing the main function, and is instead executing some other function.

So it's clear that a goroutine and a function are entirely different entities.

Do not conflate goroutines with functions!!

Functions and goroutines are entirely different concepts. And thinking of them as the same thing will lead to countless confusion and problems.
