Do you have an idea about the difference between a thread and a process?

A process is an independent execution unit with its own address space, resources, and state. A thread (goroutine in Go) is a lighter-weight unit within a process that shares the process's memory and resources but has its own stack and execution context.

In Go, a goroutine is a lightweight thread managed by the Go runtime, allowing thousands of concurrent tasks with minimal overhead compared to system threads.

Main differences:

• A process has a separate address space, while threads within a process share memory.
• Creating a process is more resource-intensive than creating a thread.
• In Go, a goroutine is a thread managed at the language level, not by the OS.

Example of creating a goroutine in Go:

func sayHello() {
    fmt.Println("Hello from goroutine")
}

func main() {
    go sayHello() // runs the function in a separate goroutine
    time.Sleep(time.Second) // wait to let the goroutine finish
}
