Go (also known as Golang) is one of the most popular languages today and is a key part of many enterprise tech stacks. Because Go's memory management architecture makes concurrency easier, many developers prefer it over traditional languages.

In this course, you will learn the core constructs and techniques of Go as well as advanced concepts of the language. In particular, you’ll learn how to program efficiently by becoming aware of the pitfalls and patterns that are commonly encountered in Go and by building your own applications.

Once you’ve completed this course, you will be able to write concurrent programs and improve the performance of existing ones, thus creating a more robust experience for everyone. Concurrency is in high demand today since it enables developers to reduce execution time of applications significantly, and Golang provides a very rich support for achieving this.

Concurrency in Go

Create a simple server that listens on port `7079` with the `/` path  and prints a simple message on the screen that says `All responses received successfully`.

- Create one function that redirects and connects the port. Use the methods `HandleFunc` and `ListenAndServe` from the `http` package for this.
- Create one function that uses the `http.Get(url)` method from the package to fetch the status of the URL.
- Create one handler function that calls the `fetchUrl` and loops over the list of URLs.
