What are the main circumstances that cause a goroutine to stop execution and disappear from the execution threads?

A goroutine in Go terminates and disappears from the execution threads in the following main cases:

• The goroutine function has completed execution — when the function launched in the goroutine returns control, the goroutine is considered finished.

• A panic that is not recovered within the goroutine — if a panic occurs in the goroutine and it is not caught with recover, the goroutine terminates abruptly.

• The program terminates — when the main goroutine finishes execution, all other goroutines also end.

Goroutines do not terminate on their own without the execution of a function or the occurrence of an error; they live as long as the code inside them is running.
