Golang Rune - Fully Understanding Runes in Go -
In today’s Golang tutorial video, we will talk about the basic runes in the Go/Golang programming language. We will go through the ASCII characters, UTF-8 in Go, and everything you need to know to fully understand how runes function in Golang. Enjoy!

Go announced Go 1.15 version on 11 Aug 2020. Highlighted updates and features include Substantial improvements to the Go linker, Improved allocation for small objects at high core counts, X.509 CommonName deprecation, GOPROXY supports skipping proxies that return errors, New embedded tzdata package, Several Core Library improvements and more.
As Go promise for maintaining backward compatibility. After upgrading to the latest Go 1.15 version, almost all existing Golang applications or programs continue to compile and run as older Golang version.

We spoke to Rob Pike, the co-author of the Go programming language, about a career spanning four decades, the evolution of Go over the last ten years, and into the future.
Evrone: Unlike many developers today, you started your career decades ago at Bell Labs. What’s been the biggest change in the way we develop software that you can think of, given your rare perspective?
**Rob: **The scale is much bigger today. Not just of the computers and the network, but the programs themselves. All of Unix version 6 (circa 1975) fits comfortably on a single RK05 disk pack, which has just over 2MB of storage, with lots of room left over for user software. And that was a fine computing environment, or at least seemed like one at the time. Although I can, of course, explain much of the growth, it is astonishing and perhaps not all of it is justified.

httppackage to create and initialize HTTPS servers in Go.
In the “Simple Hello World Server” lesson, we learned about
net/http package, how to create routes and how
[ServeMux](https://golang.org/pkg/net/http/#ServeMux) works. In the “Running multiple HTTP servers” lesson, we learned about
[Server](https://golang.org/pkg/net/http/#Server) structure and how to run multiple HTTP servers concurrently.
In this lesson, we are going to create an HTTPS server using both Go’s standard server configuration and custom configuration (using
[_Server_](https://golang.org/pkg/net/http/#Server) structure). But before this, we need to know what HTTPS really is?
HTTPS is a big topic of discussion in itself. Hence while writing this lesson, I published an article just on “How HTTPS works?”. I advise you to read this lesson first before continuing this article. In this article, I’ve also described the encryption paradigm and SSL certificates generation process.
If we recall the simplest HTTP server example from previous lessons, we only need
http.``[ListenAndServe](https://golang.org/pkg/net/http/#ListenAndServe) function to start an HTTP server and
http.``[HandleFunc](https://golang.org/pkg/net/http/#HandleFunc) to register a response handler for a particular endpoint.
In the example above, when we run the command
go run server.go , it will start an HTTP server on port
9000. By visiting
http://localhost:9000 URL in a browser, you will be able to see a
Hello World! message on the screen.
As we know, the
nil argument to
ListenAndServe() call invokes Go to use the
[DefaultServeMux](https://golang.org/pkg/net/http/#DefaultServeMux) response multiplexer, which is the default instance of
ServeMux structure provided globally by the Go. The
HandleFunc() call adds a response handler for a specific route on the multiplexer instance.
http.ListenAndServe() call uses the Go’s standard HTTP server configuration, however, in the previous lesson, how we can customize a server using
[Server](https://golang.org/pkg/net/http/#Server) structure type.
To start an HTTPS server, all we need do is to call
ServerAndListenTLS method with some configuration. Just like
ServeAndListen method, this method is available on both the
http package and the
http.``[ServeAndListenTLS](https://golang.org/pkg/net/http/#ListenAndServeTLS) method uses the Go’s standard server implementation, however, both
[Server](https://golang.org/pkg/net/http/#Server) instance and
Server.``[ServeAndListenTLS](https://golang.org/pkg/net/http/#Server.ListenAndServeTLS) method can be configured for our needs.

Golang array is a fixed-size collection of items of the same type. The items of an array are stored sequentially and can be accessed using their index. If we want to declare an array in Go, a programmer specifies the type of the elements and the number of items required by an array.
Golang programming language provides a data structure called an** array**, which can store the fixed-size sequential collection of items of the same type.
The array is used to store the collection of data, but it is often more useful to think of the array as the collection of variables of the same type.
Instead of declaring individual variables, such as no1, no2, …, and no99, you declare one array variable such as numbers and use no, no, and …, no to represent individual variables.
