What are the advantages of golang?

Go language (Golang) is a statically strongly typed, compiled, concurrent programming language with garbage collection function developed by Google. The Go language was officially open sourced in November 2009, and became TIOBE's Programming Language of the Year twice in 2009 and 2016. Go language is also a programming language that has gradually emerged in recent years. Many friends in the IT industry have begun to use go language to improve themselves after work. Why do so many people want to learn go language? What are the characteristics of go language? What are the advantages?

#golang (go) is a procedural programming language that can be used for fast machine code compilation. It is a statically typed compiled language. It provides a concurrency mechanism that makes it easy to develop multi-core and networked machine-level programs. It is a fast, dynamically typed and interpreted language; it provides support for interfaces and type embedding.

Features of golang

Simple syntax

Go language is simple and easy to learn, with a gentle learning curve. There is no need for two to three years of learning like C/C language. Go language is called "C language of the Internet era". The style of Go language is similar to C language. Its syntax has been greatly simplified based on the C language, and unnecessary expression brackets have been removed. The loop has only one expression method, for, which can realize various traversals such as numerical values ​​and key values.

Uniform code style

Go language provides a set of formatting tools-go fmt. Some Go language development environments or editors will use formatting tools to modify the format of the code when saving, thus ensuring that the code submitted by different developers is in a unified format.

Good execution performance

Go language is a compiled language. The code we write is directly compiled into a binary executable file that can be executed by the server.

High development efficiency

Although Go language is a compiled language, it has a built-in garbage collection mechanism, which reduces the mental burden on developers and makes it more efficient. It has the same development efficiency as interpreted languages ​​​​such as Python and PHP. It truly achieves the perfect combination of development efficiency and execution efficiency.

Born to support concurrency

Go was released in 2009, when multi-core processors were already on the market. The Go language has native design advantages in multi-core concurrency. The Go language natively supports concurrency from the bottom up, without the need for third-party libraries, developers' programming skills and development experience.

What are the advantages of golang

It can be directly compiled into machine code and does not rely on other libraries. The version of glibc has certain requirements. Deployment is just a matter of throwing a file up. .

A statically typed language, but with the feeling of a dynamic language. A statically typed language means that most hidden problems can be checked out during compilation. The feeling of a dynamic language is that there are many packages that can be used and written. high efficiency.

The language level supports concurrency. This is the biggest feature of Go. It is born to support concurrency. I once said that there is a difference between innate genes and plastic surgery. Everyone is equally beautiful, but you still like plastic surgery. What about innate genetic beauty? Go supports concurrency in its genes. It can make full use of multiple cores and make it easy to use concurrency.

Built-in runtime supports garbage collection. This is one of the characteristics of dynamic languages. Although GC is not perfect at present, it is enough to cope with most situations we can encounter, especially Go1.1 GC after that.

Simple and easy to learn. The authors of the Go language all have C genes, so Go naturally has C genes. Then Go keywords are 25, but the expression ability is very powerful and almost supports most of your other applications. Features seen in languages: inheritance, overloading, objects, etc.

Rich standard library, Go currently has a large number of built-in libraries, especially the network library is very powerful, and this is my favorite part.

Built-in powerful tools. There are many tool chains built into the Go language. The best one should be the gofmt tool, which automatically formats the code and makes team review so simple. The code format is exactly the same, but the thinking is different. It's all very difficult.

Cross-platform compilation. If the Go code you write does not contain cgo, then you can compile Linux applications on the window system. How to do it? Go references the code of plan9, which is information that does not depend on the system.

Embedded C support. As mentioned earlier, the author is the author of C, so Go can also directly include c code and make use of the existing rich C library.
