A goroutine is a function or method that executes concurrently alongside any other goroutines using a special goroutine thread. Goroutine threads are more lightweight than standard threads, with most Golang programs using thousands of goroutines at once.
To create a goroutine, add the go keyword before the function declaration.
go f(x, y, z)
You can stop a goroutine by sending it a signal channel. Goroutines can only respond to signals if told to check, so you’ll need to include checks in logical places such as at the top of your for loop.
