Why is golang difficult to learn?

Golang, also known as Go, is a programming language launched by Google. It is widely used in back-end development, cloud computing, containerization, blockchain and other fields. Compared with other programming languages, Golang has the advantages of rapid development, efficiency, security, and concurrency, and was once hailed as the new generation of C language.

However, in the actual learning and use process, many people find Golang difficult to learn. So, what are the difficulties in learning and using Golang? This article explores this.

1. New syntax structure

Golang’s syntax structure is relatively new compared to other programming languages. For example, it does not have the concepts of classes and inheritance, but uses structures. defined in a way. In addition, its variable declaration method is also relatively unique. For example, variables can be declared and initialized through ":=" without explicitly specifying the type. These new grammatical structures greatly improve the readability and maintainability of the code, but they also require beginners to spend more time understanding and mastering.

2. Concurrent programming

Golang is designed to be a language that naturally supports concurrent programming. In Golang, there are specialized goroutines and channels to support concurrent processing. Through goroutine, we can easily use multiple threads to perform tasks at the same time, and channels can help coordinate communication and synchronization between different goroutines. However, this natural support for concurrency also makes Golang more difficult to learn. Concurrent programming itself is a very challenging field, and for beginners, it takes more time and energy to understand and apply it.

3. Rich standard library

Golang provides a very rich standard library, covering many aspects such as network communication, encryption and decryption, and file operations. This makes it very convenient to write some basic programs without relying on third-party libraries. However, for beginners, it will be a bit difficult if they are not familiar with the characteristics and usage of various components in the standard library.

4. Documentation is not friendly enough

Although Golang’s official documentation is complete, it covers usage guides and specific details for various libraries and tools. However, compared to other programming languages, its documentation is not user-friendly. For example, when looking for some implementation methods, the corresponding method list is not provided in the document. This means that developers need to look for more third-party resources outside of official documentation. This aspect makes it more difficult for beginners to learn and use.

5. Lack of mature development ecosystem

Although Golang is widely used in cloud computing, containerization and other fields, it is not used in other fields, especially in some large software fields. , its location is not significant enough. In other words, the development ecosystem is not mature enough. Compared to some other programming languages, there are relatively few mature projects and libraries in the community. This means that if you want to complete some complex projects, you may need to spend more time building tools and frameworks.

Conclusion

The learning difficulty of Golang is indeed slightly higher than that of other programming languages. But if you are already proficient in other programming languages, then learning Golang will be relatively simple. At the same time, if you spend some time understanding Golang's design philosophy and features before learning, it will make the entire learning process easier. In addition, compared with other programming languages, Golang has been widely used in a large number of fields and has broad prospects. If you want to work in areas such as cloud computing, containerization, and blockchain, Golang is one of the essential skills.
