In this article, the editor introduces in detail "what are the basic knowledge points of Go language" with detailed content, clear steps and proper handling of details. I hope that this article "what are the basic knowledge points of Go language" can help you solve your doubts.

Go language course

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

Go was developed by Robert Griesemer, Rob Pike and Ken Thompson in late 2007, and later joined Ian Lance Taylor, Russ Cox and others. Finally, it was open source in November 2009 and released a stable version of Go 1 in early 2012. Now the development of Go is completely open and has an active community.

Go language features

Concise, fast and safe

Parallel, interesting, open source

Memory management, array security, fast compilation

Go language usage

Go is designed as a system programming language for giant central servers equipped with Web servers, storage clusters or similar purposes.

For the field of high-performance distributed systems, Go language undoubtedly has higher development efficiency than most other languages. It provides massive support for parallelism, which is great for game server development.

The first Go program

Next, let's write the first Go program, hello.go (the extension of the Go language source file is. Go), the code is as follows:

Package mainimport "fmt" func main () {fmt.Println ("Hello, World!")}

To execute Go language code, you can use the go run command.

Execute the above code output:

$go run hello.go

Hello, World!

We can also use the go build command to generate binaries:

$go build hello.go

$ls

Hello hello.go

$. / hello

Hello, World!

Expansion of basic knowledge points:

After decades of development, computer software has formed a variety of academic schools, including process-oriented programming, object-oriented programming, functional programming, message-oriented programming and so on.

In addition to OOP, some niche programming philosophies have emerged in recent years, and the Go language has also absorbed these ideas. For example, the Go language accepts some of the ideas of functional programming and supports anonymous functions and closures. For another example, the Go language accepts the message-oriented programming idea represented by the Erlang language, supports goroutine and channels, and recommends using messages instead of shared memory for concurrent programming. Overall, the Go language is a very modern language, small but very powerful.

The most important features of the Go language:

Automatic garbage collection

Richer built-in types

Multiple return values of function

Error handling

Anonymous functions and closures

Type and interface

Concurrent programming

Reflection

Language interaction
