With the wide application of Golang in various industries, more and more people are beginning to learn and use Golang to build efficient, scalable, and high-performance applications. So, what is good to learn in Golang? In response to this problem, this article will introduce the basic knowledge and necessary skills of Golang to help beginners get started.

1. Golang Basics

Before learning any programming language, it is very important to understand its basic knowledge. The following are some basic knowledge of Golang:

Syntax: Golang’s syntax is simple and easy to learn and use. It uses a simplified syntax, and you only need to master a few keywords to write simple and efficient code. For example: variable declaration, flow control and function definition, etc.

Data types: Golang’s data types include basic data types and composite data types. Basic data types include integers, floating point numbers, Boolean values, and strings, etc. Composite data types include arrays, slices, maps, structures, etc.

Function: Golang's functions are very flexible and can be used as first-class citizens. It supports features such as function transfer, anonymous functions and closures, and can support different programming styles such as object-oriented and functional programming.

Concurrency: Golang is a programming language that emphasizes concurrency. Its goroutine mechanism can support concurrent operations with limited resources without the need to create and destroy expensive resources like traditional threads. In addition, Golang also supports mechanisms such as atomic operations and channels to ensure concurrency safety.

2. Golang essential skills

In addition to basic knowledge, there are also some essential skills that Golang programmers need to master. Here are a few of them:

Package Management: Golang has its own package management mechanism that can easily manage dependencies. Mastering the package management tools go mod and dep can help programmers better manage project structure and dependencies.

Tool chain: Golang provides a complete set of tool chains, including compilers, static analysis tools, testing tools, performance analysis tools, etc. Being proficient in these tools can greatly improve your work efficiency.

Testing: Testing is an important part of Golang program development. Mastering different levels of testing methods, such as unit testing, integration testing, and end-to-end testing, can help programmers write more robust and reliable code.

Web development: Golang has certain advantages in the field of Web development. Mastering the web frameworks beego, gin, and echo can help programmers easily build high-performance web applications.

Database: Golang supports a variety of databases, including relational databases and non-relational databases. Mastering the methods of interacting with databases, including using the ORM (Object-Relational Mapping) framework for database operations, connecting and using various types of databases, can help programmers better manage data.

Conclusion

In short, if you want to learn and use Golang, you need to master its basic knowledge and necessary skills. At the same time, continuous learning and accumulation of experience, participation in community activities and exchanges can accelerate growth and better cope with challenges at work.
