Is the main() Function in Go a Goroutine?

Is the main Function a Goroutine?

The question stems from confusion around the concept of goroutines in Golang. The crash stack trace provided raises the query of whether the main() function operates as a goroutine.

However, the answer is clear: no, the main() function is not a goroutine. It is a function. A goroutine, on the other hand, is a lightweight thread of execution that encompasses functions.

To clarify further, the main() function is executed within the first goroutine (number 1) during program startup. Nevertheless, when main() invokes a subsequent function, the original goroutine no longer executes the main() function but transitions to the newly invoked function.

Therefore, it is evident that goroutines and functions are distinct entities. Equating them can result in substantial misconceptions and complications. Remember, functions and goroutines are separate concepts that must not be conflated.
