golang is nothing more than that

As one of the most popular programming languages ​​in recent years, Go (or Golang) has received widespread attention and use. In the eyes of many developers, Go is a language that is easy to learn, efficient and reliable, and takes into account both scale and efficiency. However, there are also those who believe that Go is not as good as its reputation suggests. They believe that Go is just a small language that has emerged in the past few years. Although it can achieve better results in some scenarios, it is not worth placing all the bets on it.

These opposing views make us think about whether this language is overrated. Let’s analyze and discuss this issue from three levels: design philosophy, language features, and ecosystem.

1. Go’s design philosophy

The Go language was originally initiated by Google. Its design had one purpose: to develop large-scale software efficiently in a more modern way to cope with the current situation. Development challenges faced.

Go is designed with simplicity (easy to learn), efficiency (compilation speed and execution speed are very fast), and reliability (robustness, type safety, concurrency safety) as its design principles. It also follows the tradition of C language: fast Compile and keep your code efficient. These design philosophies are reflected in the Go language, such as its garbage collection mechanism, concurrent programming mode, error handling mechanism, etc.

Go also handles some common defects in the C language, such as pointer operations or illegal memory access. In addition, Go has good scalability and supports both static and dynamic linking methods. Therefore, Go has good cross-platform features and can be easily compiled and run on different operating systems and hardware platforms.

Because of its efficient and reliable design concepts, as well as its compatibility with C language and other excellent features, more and more people are beginning to use and like Go. However, this does not mean that Go is without flaws.

2. Go’s language features

Go has unique features compared to other programming languages. One of its most obvious features is its concurrent programming model.

Go's concurrent programming model uses the implementation of goroutine and channel, which can provide faster and more efficient concurrent processing methods and eliminate a large number of locks, synchronization and other problems that exist in the traditional multi-threaded programming model. It also has the advantage of being able to easily handle blocking issues. This makes Go a powerful concurrent programming language, more suitable for building high-concurrency services.

At the same time, Go also has type safety and generics features. Go provides generic support through reflection, but compared to other languages, its generics are still relatively weak, so in some cases, users need to manually implement data structures and algorithms by themselves.

However, Go’s type system is indeed relatively weak, and in many cases manual type conversion is required, which also slightly reduces the effect of static type checking. At the same time, there is no such concept as a class in the language, and enumerations can only be replaced by constants. This can make Go a bit cumbersome in some situations.

Go also does not provide inheritance and method overloading in object-oriented programming. Although Go provides interface-like interface types, they are relatively complex to use and require writing additional code to achieve the same functionality.

3. Go’s ecosystem

In addition to the characteristics of the language itself, the ecosystem is also an important criterion for measuring the valuation of a programming language. Although Go's ecosystem is relatively new, its open source community is constantly growing.

In the field of web back-end development, Go is popular for its efficient concurrent programming model. There are already many well-known applications developed using Go language, such as: Docker, Kubernetes, Etcd, Caddy, InfluxDB, etc. At the same time, in the field of cloud computing, Go is also developing very rapidly.

However, compared with established languages ​​​​such as Java, Go’s ecosystem seems to be still in its infancy. Compared to dynamic programming languages ​​like Java or Python, there don't seem to be that many libraries and frameworks available in Go's ecosystem, which may bring some limitations when developing certain applications, or require you to build some wheels yourself.

Conclusion

In short, Go is an excellent programming language that is widely used in the construction and development of large-scale distributed systems. The simplicity and efficiency of the Go language give it obvious advantages in certain application scenarios.

However, Go is not the most suitable programming language for all scenarios. For example, Node.js may be a better choice when developing heavily I/O-intensive applications. At the same time, for developers with large applications that are deeply embedded in languages ​​like C or Java, adopting Go may require rethinking and refactoring their code. In addition, since Go's ecosystem is not yet so large and complete, you may need to write more custom code, which may be inconvenient in some scenarios.

To sum up, the success of Go will depend on multiple factors such as application scenarios, team skills, and developer personal preferences. For Go, it is not appropriate to be overly enthusiastic or overly critical. We need to choose the most suitable programming language based on actual needs.
