What do you need to learn in golang?

Go language (also Golang) is a developed programming language, led by Google. It has become a very popular language in recent years because of its good readability, easy writing and cross-platform characteristics. Programming languages ​​are widely used, especially in the fields of cloud computing and big data.

So, for developers who are ready to learn or have already started learning Golang, what should they learn? In the following article, we will introduce in detail all aspects of Golang that you need to learn.

1. Basic syntax

As a programming language, you first need to understand its basic syntax, such as variable declaration, function definition, process control, etc. The basic syntax of Go language is relatively simple and is not difficult to learn. However, without mastering basic grammatical knowledge, it will be difficult to further understand and apply the language.

2. Concurrent programming

Golang is a language that supports concurrent programming and is excellent at writing concurrent programs. Learning concurrent programming can help you better understand Golang, and can also allow you to make more effective use of computer resources and improve application performance when writing applications using Golang.

Knowledge of concurrent programming includes but is not limited to: coroutines, channels, locks, etc. A coroutine is a lightweight thread that is automatically managed by the Go language runtime system and can run multiple coroutines simultaneously in one thread. A channel is a mechanism used for communication between coroutines. Channels can be used to safely transfer data between coroutines. A lock is a synchronization mechanism used to protect shared resources from being accessed by multiple coroutines at the same time.

3. Garbage Collection

Golang is a memory-safe language that provides a garbage collection mechanism and automatically manages memory allocation and release. Learning garbage collection can give you a better understanding of how Golang works in terms of memory management, and can also avoid some common memory leaks and memory overflow problems.

4. Package Management

When writing Golang applications, it is often necessary to introduce some external packages, such as third-party libraries. Therefore, it is very important to learn package management. Golang's package management system uses the Go Modules mechanism, which allows you to easily manage your dependencies while ensuring the correctness of your program in different environments.

5. Database operation

Like other programming languages, Golang also has good database support. Learning database operations can give you a better understanding of how Golang works in terms of data storage and retrieval, and can also help you use Golang to write database applications more effectively.

Currently, commonly used databases in Golang include MySQL, PostgreSQL, MongoDB, etc.

6. Web Programming

Golang also has a very good performance in Web applications. It provides its own Web framework-gin, which allows you to easily write high-level applications. Performance web applications. Learning web programming allows you to better use Golang to write web applications, and you can also master some common web development technologies, such as HTTP protocol, RESTful API, etc.

7. Coding specifications

Coding specifications are a very important part of programming, which determines the quality and readability of your code. In Golang, coding standards are also very important. Learning Golang's coding standards allows you to write high-quality, easy-to-maintain code.

How to learn Golang

The above are all aspects that need to be learned in Golang. It should be noted that learning any programming language requires a certain amount of patience and time. To learn Golang, it is recommended to use a variety of methods, such as:

1. Learn related books and documents
2. Participate in online or offline training
3. Write some simple applications To strengthen practice
4. Refer to excellent Golang programs

As Golang’s popularity in China gradually increases, there are currently many online learning resources for developers to refer to. You can find many open source projects written in Golang on the Internet, such as ETCD, Docker, Kubernetes, etc.

Summary

Golang is a programming language that is worth learning. It not only performs very well in terms of performance and readability, but is also very suitable for application development in fields such as cloud computing and big data. . Although the learning curve of Golang is slightly steeper than other languages, as long as you have a step-by-step learning method and practical experience, I believe you will become an excellent Golang programmer.
