Golang’s syntax is simple and clean. Golang is a process-oriented language. It has no concept of classes and its syntax is relatively simple and straightforward. The most intuitive feeling of Golang is that it is concise (less language details), efficient (rapid development) and high-performance (ignore GC, analogy to C performance).

Golang is a process-oriented language. It has no concept of classes and its syntax is relatively simple and straightforward.

Golang inherits many C language styles. The most intuitive feeling of Golang is simplicity (less language details), efficiency (rapid development) and high performance (when GC is ignored, the performance is similar to C).

Go language - a rising star from a well-known family

The Go language was born at Google and was developed by Rob Pike, three masters in the computer field. , Ken Thompson and Robert Griesemer. Due to its famous background, Go attracted the attention of a large number of developers at the beginning of its birth.

But Go’s language advantages are indeed the reason why it still has a large number of followers.

1, simple and efficient

As a rising star, Go language has the characteristics of simple syntax and high execution efficiency at the language level; in comparison, Java, Python, and PHP All seem inefficient, C is too cumbersome, and Go can achieve both simplicity and efficiency.

2, high concurrency

The Go language focuses on concurrency and is born for concurrency. Its starting point is to target high concurrency and high concurrency in the era of big data cloud computing. Distributed application scenarios.

3, cross-platform

can be directly compiled to generate executable programs on different platforms. The basic memory usage is very small, small applications take up a few M, and large applications take up a few M It can run very well with only 10 MB, which allows golang to run very well on small devices such as Raspberry Pi, which performs much better than Java.

Domestic applications of Golang language

Today’s Toutiao, more than 80% of the current back-end service traffic of Today’s Toutiao is running services built in Go superior. The number of microservices exceeds 100, the peak QPS exceeds 7 million, and the daily processing requests exceed 300 billion. It may be the largest Go application in the industry.

These companies are using Go:

1. Google

This needs no further introduction. As a company that develops the Go language, it does its job. Google has many excellent projects based on Go, such as: https://github.com/kubernetes/kubernetes. You can also view more Google's Go open source projects on Github at https://github.com/google/.

2. Facebook

Facebook also uses it. For this reason, they have also established an open source organization facebookgo on Github. You can use https://github. Visit com/facebookgo to view Facebook’s open source projects, such as the famous grace that provides smooth upgrades.

3. Tencent

As a large domestic company, Tencent still dares to try, especially in the field of Docker containerization. They have done tens of thousands of docker projects in 2015. For Taiwan-scale practice, please refer to http://www.infoq.com/cn/articles/tencent-millions-scale-docker-application-practice.

Golang’s application fields

1. Server programming, before you If you use C or C to do those things, it is very suitable to use Go to do it, such as processing logs, data packaging, virtual machine processing, file systems, etc.

2. Distributed systems, database agents, etc.

3. Network programming, this area is currently the most widely used, including Web applications, API applications, and download applications.

4. In-memory database, part of groupcache and couchbase developed by Google some time ago.
