What types of parallel task implementations do you know?

In Go, parallel tasks can be implemented in several ways:

• Goroutines — lightweight threads that are started with the go keyword. They allow functions to run concurrently.

• Channels — used for communication and synchronization between goroutines, enabling safe data transfer.

• Worker pools — a pool of goroutines that take tasks from a queue and process them, helping to control the number of goroutines running simultaneously.

• sync.WaitGroup — used to wait for a group of goroutines to finish.

Example of launching a goroutine and passing data through a channel:

ch := make(chan int)
go func() {
    ch <- 42 // send value into the channel
}()
val := <-ch // receive value from the channel
fmt.Println(val)
