Explore some common Golang flaws and controversies

GO language (Golang) is an open source programming language developed by Google. It is designed to solve some problems that exist in other programming languages, such as memory leaks, performance issues, etc. Although Golang is an emerging programming language, it is already loved by many developers and is widely used to build high-performance and scalable services.

However, in the rapid rise of Golang, some people are dissatisfied with it. They believe that Golang has some limitations that may make it unsuitable for certain workloads. In this article, we will explore some common Golang flaws and controversies and try to resolve them.

1. Lack of generics
The lack of generics in Golang has become one of the issues of widespread concern. Generics are a programming language feature that makes code more reusable and safer. Generics allow us to write more general functions and data structures without having to worry about type safety issues.

In Golang, due to the lack of generic support, type conversion must be used when we need to process different types of data. This can lead to code that becomes more complex, difficult to maintain, and error-prone.

While the lack of generics in Golang is problematic, some recent developments suggest that this problem may not be far away. Go 2 has added support for generics and is actively developing it, and by then we may see Golang being able to better solve this problem.

2. Performance issues
Although Golang has always been promoted as a high-performance language, in some cases, we may find that Golang is not the best choice. Because Golang uses a garbage collection mechanism, this means that the program needs to allocate and release memory at runtime. This can cause performance bottlenecks, especially if large amounts of data need to be processed.

In addition, Golang lacks optimization for multi-core processors, which may make its performance inferior to other languages ​​when handling large-scale calculations.

However, as with other programming languages, performance issues are often related to architecture, algorithm and code implementation. If we are able to use appropriate technologies and best practices, we can still build high-performance and scalable systems in Golang.

3. Package management
Golang’s original package management tool is go get, which is a simple and easy-to-use tool that allows us to download dependencies and put them into a specified directory. However, over time, as the code base has grown, go get has become increasingly difficult to manage.

Some developers have turned to third-party solutions, such as Glide or dep, which use tools from other languages ​​as a source of inspiration to provide more powerful and flexible package management capabilities.

Recently, Golang officially launched the new package management tool go mod, which is considered to be one of the largest changes in the history of Golang package management. go mod allows us to get dependencies from different sources, making it easier to manage, and allows us to have better control over features and versions.

Conclusion
Although Golang has some common flaws and controversies, we cannot deny its importance and practicality. In fact, Golang has been widely used in various fields, including microservices, cloud computing environments, and blockchain.

Although Golang is not perfect, we can take various methods to solve its shortcomings. More importantly, we should realize that every programming language is full of pros and cons, and we need to choose the best tool for the specific task.
