Is it possible to run multiple goroutines simultaneously in one application?

Yes, in Go, you can run multiple goroutines simultaneously within a single application. A goroutine is a lightweight thread managed by the Go runtime, allowing functions to execute concurrently. For example, you can launch several goroutines for data processing or network requests:

 go func() {
    fmt.Println("Goroutine 1")
}()

go func() {
    fmt.Println("Goroutine 2")
}()

// To prevent the main thread from finishing before the goroutines
time.Sleep(time.Second)

The Go runtime efficiently distributes goroutines across system threads, ensuring concurrent execution.
