How to learn the basics of golang well

Go language (Golang) is an emerging high-level programming language, and its emergence has been widely welcomed and supported. As a new programming language, learning Go will open up a new world for you and open a door to career development.

If you want to learn the basics of golang, then this article will provide you with helpful suggestions and guidance. I will share my learning experience and some key points in my opinion to help you master the basics faster and better in the process of learning Golang.

Set up your environment

Before you start learning Golang, you need to set up the environment. In most cases, installing the Go language is a very quick and easy process. You can download the Go language version suitable for your operating system from the official website. Unzip the installation package to the directory you set to start using the go command line compiler.

Before you start writing code, you need to learn to use some basic tool information. These include: command line packages, operating system packages, and file system packages. These packages provide basic functionality such as receiving and outputting content, creating and running programs, and creating and using files.

Learn basic syntax

If you are already proficient in other programming languages, some Golang syntax and coding styles may be similar and easy to learn. For example, Golang's variable declaration and definition methods are similar to other languages, and package block declarations are also similar.

In Golang, you need to know some common keywords, such as: variable type declaration, constant definition, array and slice definition, loop statement, judgment statement, etc. At the same time, you need to pay attention to the special syntax aspects of Golang, such as: an if statement must be prefixed with parentheses, etc. Because Golang's syntax is relatively simple, it is easy to master.

Write and run programs

After you are familiar with the basic syntax of Golang, you need to write and run some Golang programs. This can help you deeply understand the working principles and rules of Golang.

You can try to write a simple "Hello World" program to verify your Golang installation and settings. During the execution of the program, you will encounter some error messages, which help you check for errors in the code and show you some basic information about Golang.

Reduce repetitive work

In the process of writing programs, you will find that you often have to write the same code. You can write functions to reduce the duplication of code. You can also encapsulate code that needs to be repeated into a container and create a reusable code library. The time saved in this way allows you to spend more energy on learning, thinking and implementing more practical work.

Mastering pointers and types

In Golang, pointers are not as complicated as in some other languages. Pointers as types can be used to pass and manipulate memory addresses, so it is very important to understand pointers.

Type conversion is also another important concept in Golang. When you manipulate variables of different types, you need knowledge of type conversion to make your code work correctly.

Continue learning

Once you have mastered the basics of Golang, you should find that there is still a lot more you need to know. A good direction is to continue learning Golang's standard library and various packages, which will allow you to expand your skills and build more practical programs.

In addition, you should also spend time reading other people's code and participating in forums, social media, and other online communities to gain a deeper understanding of all aspects of Golang. These discussions will give you insight into more details and other learning resources that can help you improve your skills, ultimately making you a better programmer.

Conclusion

The learning (curve) path of Golang may vary from person to person, but these basic points can be used as suggestions and guidance for you to get started. These tips will help you master the basics of Golang and lay a good foundation for your career development. If you can continue to learn and apply what you have learned into practice, then you will become an excellent Golang programmer.
