1 Introduction
Go (also known as Golang) is a statically strongly typed, compiled, and garbage collection programming language developed and open sourced by Google. It is mainly aimed at building fast, reliable, and efficient distributed system applications. Its design philosophy focuses on simplicity, and its syntax and standard library make it easy to learn and use. Currently, Go has become one of the most popular languages in cloud computing, microservices, container orchestration and other fields. Applications in fields such as big data, artificial intelligence, blockchain, and the Internet of Things are also very popular. Go language will undoubtedly become a milestone in the future development of the Internet. This article mainly introduces the Go language and records some tips for using Go. I hope it can help readers better understand this programming language and how to use it.
