Is golang fast?

The Go language (or Golang) originated in 2007 and was officially released in 2009. Go is a very young language, and its main goal is to "combine the development speed of dynamic languages ​​such as Python and the performance and safety of compiled languages ​​such as C/C."                                                                                                                           (Recommended learning: go)

Go language is another attempt at programming language design and a major improvement to C-like languages. , also provides powerful network programming and concurrent programming support. Go language has many uses and can be used for network programming, system programming, concurrent programming, and distributed programming.

The launch of Go language aims to reduce the complexity of the code without losing application performance. It has the advantages of "simple deployment, good concurrency, good language design, and good execution performance". Currently, many domestic IT companies have adopted Go language to develop projects.

The Go language is sometimes described as a "C-like language", or "the C language of the 21st century". Go inherits similar expression syntax, control flow structure, basic data types, call parameter value transfer, pointers and many other ideas from C language. It also has the running efficiency of compiled machine code that C language has always valued and is consistent with existing Seamless adaptation to the operating system.

Because the Go language does not have the concepts of classes and inheritance, it does not look the same as Java or C. But it achieves polymorphism through the concept of interface. The Go language has a clear and easy-to-understand lightweight type system, and there is no hierarchy between types. Therefore, it can be said that Go language is a hybrid language.

In addition, many important open source projects are developed using the Go language, including Docker, Go-Ethereum, Thrraform and Kubernetes.

Why you should learn Go language

If you want to create system programs or network-based programs, Go language is a very good choice. As a relatively new language, it was designed by experienced and respected computer scientists to address the challenges of creating large-scale concurrent network programs.

Before the emergence of the Go language, developers were always faced with a very difficult choice: whether to use a language (such as: C) that has fast execution speed but unsatisfactory compilation speed, or use a language that has fast compilation speed but not ideal compilation speed. What about languages ​​with poor execution efficiency (such as .NET, Java), or dynamic languages ​​that are less difficult to develop but have average execution speed?

Obviously, Go language achieves the best balance between these three conditions: fast compilation, efficient execution, and easy development.

The Go language supports cross-compilation. For example, you can develop applications that can run on Windows on a computer running a Linux system. This

is the first programming language to fully support UTF-8. This is not only reflected in the fact that it can handle strings encoded using UTF-8, but even its source file format uses UTF-8. coding. Go language is truly international!
