Why do many companies turn to Golang? Are Java, Python, and C# declining?

Go language is the second open source programming language released by Google in 2009.

The Go language is specially optimized for programming multi-processor system applications. Programs compiled using Go can be as fast as C or C++ code, are more secure, and support parallel processes.

Why do many companies turn to Golang? Are Java, Python, and C# in decline?

When choosing a development language for a project, focus on performance, improvement of the language technology stack, development efficiency, and language learning costs.

Choose golang for many reasons

How is the performance: Golang’s performance is relatively high, and qps, which does not require a framework to write an API, can be comparable to nginx. This kind of performance is unmatched by python.

Language technology stack: Golang’s development technology stack is also very complete, and all required common components can be found on github.

Development efficiency: Some coders who love C/C++ know that C/C++ development efficiency is not high, and go can solve the problem of development efficiency.

A senior engineer said that he has been developing system software in C language for more than ten years. Now I will use go wherever Go can be used (except for the kernel). Nothing else. Two reasons:

1. Compared with c/c++, development efficiency is greatly improved, with built-in garbage collection, asynchronous, closure, etc. In addition, various built-in libraries are easy to integrate with the web side, which is very suitable for quickly building large systems.
2. Static linking achieves complete decoupling of application deployment and OS version. Don’t underestimate this. In a complex system, just the versions of various libraries can kill people.

Yunfeng, an expert in the industry, also said in his blog:

“I found that I spent four years honing my ability to build systems in C language, trying to find a specification that could better write software. It turned out that it was just an imitation of Go. Lack of language-level support, I could only It’s a poor imitation.”

Learning cost: With a C foundation, it is very easy to learn Golang. The synchronous method can easily achieve high concurrency. The code is concise, the format is unified, and it is easy to read. While the performance is strong, the development efficiency is not inferior to dynamic languages ​​​​such as Python.
