Golang (also known as Go) is an open source, efficient, and concurrent programming language. With the advent of the era of cloud computing and big data, Golang has gradually become popular in fields such as high concurrency and large-scale distributed systems. Whether you want to improve your programming skills or further develop your career, turning to Golang is a good choice. This article will introduce some basic knowledge, learning resources and practical experience of Golang to readers to help readers make a better transition to Golang.
1. Basic knowledge of Golang
Golang supports constants and variables. Constants refer to values that do not change while the program is running, while variables can be assigned and modified while the program is running. To declare a variable, you can use the var keyword, for example:
var age int age = 29
To declare a constant, you can use the const keyword, for example:
const pi float32 = 3.1415926
Golang There are many data types, such as integer, floating point, Boolean, string, etc. Among them, integer types can be divided into different types such as int, int8, int16, int32, int64, etc., while floating point types can be divided into different types such as float32, float64, etc. The Boolean type has only two values, true and false. A string is a sequence of characters enclosed in double or single quotes.
A function in Golang starts with the keyword func and contains a function name, parameters and return value. For example:
func Add(a int, b int) int { return a + b }
Loops and conditional statements in Golang are similar to other programming languages. The if statement is used to determine whether the condition is true, and the for statement is used to execute the code block in a loop. For example:
if age >= 18 { fmt.Println("成年人") } else { fmt.Println("未成年人") } for i := 1; i <= 10; i++ { fmt.Println(i) }
2. Learning resources
Golang official provides complete documentation and tutorials, from entry to mastery. guidance. On the official website, you can find detailed information about Golang's installation, environment configuration, language features, standard library and other information. The official documentation also provides online tutorials, where you can learn Golang's syntax and features in an interactive way.
In addition to official documents, there are also some online resources that can help you learn Golang. For example, in the Go Playground officially provided by Golang, you can try to run the code online and view the running results. There are also some community websites, such as GitHub, Stack Overflow and Reddit, where you can obtain the latest learning materials and exchange Golang-related issues.
There are some excellent Golang books that can help you learn Golang more deeply. For example: "Go Programming Language", "Go Language Programming", "Go Web Programming", etc.
3. Practical experience
Only through practice can you truly learn a programming language. You can start from easy to difficult, start by writing some simple code, and gradually increase the difficulty, such as writing a small tool or a simple Web application.
Learning open source projects can let you understand the use and characteristics of Golang in practical applications, and can improve your practical capabilities. You can find some excellent open source projects from websites such as GitHub and try to read and understand the code.
The Golang community is very active and you can participate in some related technical exchange activities, such as meetups, technical lectures, etc. At the same time, you can also write your own experiences and insights into a blog or share them on social media to help others learn Golang.
Summary:
Golang is an excellent programming language with the characteristics of high concurrency, high efficiency, and easy to learn. If you want to switch to Golang, you need to master the basic knowledge, learning resources and practical experience of Golang. Through continuous practice and learning, as well as active participation in community exchanges, I believe that I will switch to Golang faster and achieve more achievements in this field.
