1, Go language introduction:
(1) The Go language is the second open source programming language released by Google 2009.
(2) The Go language is optimized for programming multi-processor system applications, with go-compiled programs that are comparable to the speed of C or C + + code, and are more secure and support

This is because the high concurrency of the go coroutine attracts me.
And google language. I believe that he will develop well in the future. So let's take a look.
Of course, language is a virtual thing. The main thing is the understanding of programming thinking.
Therefore, I do not recommend learning the syntax of a language and learning another language. It is best to spend enough time studying a language. It is mainly about programming patterns.
