How to learn golang development

With the continuous development of software development technology, more and more developers are beginning to learn the programming language golang (also known as Go). Compared with other programming languages, golang has excellent performance and high efficiency. Its concise syntax and concurrent programming provide a simple and efficient way to build excellent software.

So, how does golang learn? In this article, we will explore the basics of golang, as well as the best practices for learning golang.

1. Getting Started Guide

Before learning golang, it is recommended that you understand the following knowledge:

• Programming basics: Understand the basics of computer science, including algorithms and data structures , computer network, etc.
• Linux basics: golang is the most commonly used on Linux operating systems, so it is recommended that you have a good understanding of Linux basics.
• Code Editor: Choose a code editor you like (such as VS Code, Sublime Text, etc.).

If you meet the above conditions, then you can start learning golang.

2. Learning resources

The key to learning any programming language is to choose good learning resources. The following are recommended learning resources for golang:

1. Official documentation: Golang officially provides very detailed documentation, including language specifications, standard libraries, tools, etc. As a beginner of golang, you should first read the official documentation.

2.Gobyexample: Gobyexample is a good place to learn golang. It provides a series of easy-to-understand examples covering multiple aspects of golang. Reading these examples will help you gain a deeper understanding of the basics and usage of golang.

3.Golangbot: For beginners, Golangbot is a good online tutorial. It covers Golang's basic syntax, control flow, functions and pointers, and provides some exercises and quizzes to test your understanding.

4. Udemy course: If you want to learn golang systematically and master related skills, you can consider learning a golang course from Udemy. These courses are written by experienced developers and explain in simple terms.

3. Development environment configuration

Before learning golang, you need to ensure that golang has been installed on your computer. You can download the corresponding version of golang from the golang official website.

Configure golang's environment variables. You can check whether the installation is successful by entering the following command on the command line:

$ go version

If the system successfully outputs the golang version number, it means you have successfully installed golang.

4. Learning the basic knowledge of golang

Learning the basic knowledge of golang is the first step for beginners to learn golang. The following are the basics of golang:

1. Variables and types

In golang, variables must be explicitly declared. Golang has many basic types, including integers, Boolean values, strings and floating point numbers. The type of the variable must be specified explicitly.

For example:

var i int = 10
var s string = "Hello World"
var b bool = true

2. Function

In golang, a function is an independent block of code used to perform specific tasks. Each function in golang consists of function name, parameter list and return type.

For example:

func Add(a int, b int) int {

return a + b

}

3. Conditional statement

golang Conditional statements in include if, else, elseif and switch. The if statement is used to execute a single block of code or multiple blocks of code. Within a block of code, the if statement checks whether a condition is true or false.

For example:

if a > b {

fmt.Println("a is larger than b")

} else {

fmt.Println("b is larger than a")

}

4. Loop statement

Loop statements in golang include for and range. The for statement is used to execute a loop and allows the loop condition to be variable.

For example:

for i := 0; i <= 5; i {

fmt.Println(i)

}

5. Practical exercises

Practical exercises are one of the best ways to learn any programming language. The following are several practice projects that can help you gain a deeper understanding of the basics of golang:

1. Build a simple command line application
This application allows the user to enter an integer and then calculate the integer squared.

2. Create a simple url shortening service
The application needs to receive the url entered by the user and generate a short url for shortening it. It also needs to provide a way to restore the short url to the original url.

3. Create a simple web service
This application needs to use golang's built-in Web and HTTP packages to create a simple web service. The user can enter some text and click a button, and the text can be sent to the server and displayed on the web page.

6. Continuous learning

Learning never stops. After mastering the basic knowledge of golang, you can further understand golang's advanced features and libraries. For example, learn concurrent programming, golang's built-in features, network programming, etc. You can read golang official documentation, participate in the golang community, and communicate with other developers to learn more.

Summary

Golang has become a popular programming language that is simple, efficient, fast and easy to use. Learning golang requires some basic knowledge, good learning resources and practical exercises. But as long as you study seriously, continue to explore and learn, you will become an excellent golang developer.
