This article is about how to understand the basic Go language entry applications and commonly used commands, the editor feels very practical, so share with you to learn, I hope you can learn something after reading this article, say no more, follow the editor to have a look.

Brief introduction of Go language

Go is an open source, concurrency, garbage collection compiled system programming language developed by Robert Griesemer,Rob Pike,Ken Thompson in late 2007, and later joined lan Lance Taylor,Russ Cox et al., finally opened source in November 2009, and released a stable version of Go 1 in early 2012.

Main features of Go language [key points]

Object-oriented without inheriting polymorphism

Strong consistency type

Interface does not need to display a declaration

No exception handling

Acronym-based accessibility

Unused import or variables cause compilation errors

Perfect and excellent standard library package

Go language is a compiled statically typed language, which can manipulate memory directly through pointers.

Type safety and memory security

Achieve high concurrency [concurrent programming] in a very intuitive and very low-cost solution

Efficient garbage collection mechanism (built-in runtime)

Fast compilation (also solves the problem of too many header files in C language)

A scheme function that provides performance improvement for multicore computers can return multiple values

Application of Go language

Server programming: dealing with logs, data packaging, file systems, etc.

Distributed systems: database processors, middleware, etc.

Network programming: the most widely used piece at present, Web application, API application, etc.

Cloud platform: at present, the cloud platform is gradually implemented with Go

Block chain development

Large-scale game server development

Commands commonly used in Go language

Go get: get the remote package (need to install git or hg in advance)

Go run: run the program directly

Go build: project release

Go fmt: formatting source code (some IDE is automatically called when saving)

Go install: compile the package file and compile the entire program

Go test: running test files

Go doc: viewing document

Go help: viewin

Go Command Line

Visibility rules in Go language [key]

In Go, case is used to determine whether the constant, variable, type, interface, or structure can be called externally.

The first letter of the function name is private in lowercase, and the first letter of the function name is public.

The above is how to understand the basic application of Go language and common commands. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
