Is it possible to transfer a task from one goroutine to another that is in a idle state?

In Go, you cannot directly pass a task from one goroutine to another that is in a idle state, because goroutines do not have a built-in mechanism for task transfer.
However, to organize task transfer between goroutines, channels are usually used. One goroutine can send tasks into a channel, and another can receive and execute them. If the goroutine receiving tasks is idle, it will wait for data from the channel and process it immediately upon arrival.
Example:
tasks := make(chan func())
// Worker goroutine
go func() {
for task := range tasks {
task() // execute the task
}
}()
// Sender goroutine
tasks <- func() {
fmt.Println("Task completed")
}
Thus, the task is transferred via the channel, and the goroutine waiting in an idle state receives and executes it.
