Explain the concept of Goroutines and how they enable lightweight concurrent programming in Go.

In Go, Goroutines are a fundamental feature that enables lightweight concurrent programming. Goroutines are lightweight threads of execution managed by the Go runtime. They allow concurrent execution of functions or methods, providing a simple and efficient way to handle concurrent tasks in Go programs. Unlike traditional threads or operating system processes, Goroutines are not mapped one-to-one with system threads. Instead, they are multiplexed onto a smaller number of operating system threads. This means that Goroutines can be created and destroyed with minimal overhead, making them highly efficient in terms of memory usage and context switching. The concept of Goroutines is closely tied to the concept of channels in Go, which are communication primitives that enable safe and synchronized communication between Goroutines. Channels facilitate the sharing of data and coordination between Goroutines, enabling them to communicate and synchronize their execution. The syntax for creating a Goroutine is quite simple. It involves using the `go` keyword followed by....
