What can golang do?

Go is a language launched by Google in 2009. It is designed as a system programming language for giant central servers equipped with web servers, storage clusters or similar purposes.

For the field of high-performance distributed systems, the Go language undoubtedly has higher development efficiency than most other languages. It provides massive parallel support, which is perfect for game server development.

To date, the development of Go is completely open and has an active community.

Why so many people prefer Go language:

In addition to the above-mentioned industry giants, Go language is also popular among many domestic cloud startups, such as DaoCloud. So why did they choose Go? What advantages does it have compared to applications in other languages?

1. Learning curve

It includes C-like syntax, GC built-in and engineering tools. This is very important because the Go language is easy to learn, so an ordinary college student can write a usable, high-performance application in one week. Everyone in China pursues speed, which is one of the reasons why Go is so popular in China.

2. Efficiency

Go has an operating efficiency close to C and a development efficiency close to PHP, which greatly supports everyone's pursuit of speed.

3. Come from a well-known family and have pure blood

The reason why Go comes from a well-known family is because we know that the Go language comes from Google. Needless to say, this company's popularity and strength in the industry go without saying. Google has gathered a group of talented people to launch a new programming language in a situation where various programming languages ​​are competing for hegemony. Naturally, it has its own strategic considerations. And judging from the development trend of the Go language, Google still attaches great importance to its new darling. Go naturally has a good development future. If we look at the main creator of the Go language, we can see that he has pure blood.

4. Free and efficient: the idea of ​​combination, non-intrusive interface

The Go language can be said to be the perfect fusion of development efficiency and operating efficiency. , native support for concurrent programming. The Go language supports all current programming paradigms, including procedural programming, object-oriented programming, and functional programming. Programmers can get what they need, combine them freely, and play whatever they want.

5. Powerful standard library

This includes Internet applications, system programming and network programming. The standard libraries in Go are basically very stable, especially the three libraries I mentioned here, the network layer and system layer libraries are very practical.

6. Convenient deployment: binary files, Copy deployment

I believe this is the biggest reason why many people choose Go. Because deployment is so convenient, many people now use Go to develop and operate. dimension program.

7. Simple concurrency

It includes mental-reducing concurrency and simple data synchronization. I think this is the biggest feature of Go. The reason why it is so difficult to write correct concurrent, fault-tolerant and scalable programs is because we use the wrong tools and wrong abstractions. Go can be said to do this quite easily.

8. Stability

Go has powerful compilation checks, strict coding standards and complete software life cycle tools. It has strong stability, and stability trumps everything else. So why is Go more stable than other programs? This is because Go provides tools for each aspect of the software life cycle (development, testing, deployment, maintenance, etc.), such as go tool, gofmt, go test.

Here is a quote from a classmate on Zhihu who commented on Go: When I was first preparing to go online, I was actually quite nervous. After all, if something goes wrong, not only would I have to take the blame, but I would also lose face. Fortunately, the results are pretty good. There has not been a single sudden BUG since it went online, which not only reduces the difficulty of operation and maintenance, but also reduces the load on the machine. I believe this is also the reaction of most people after using Go.

What can golang do?

Many friends may know the advantages of Go language, but they don’t know where Go language is suitable for use.

In fact, the Go language is mainly used for server-side development. It is positioned to develop "large-scale software". It is suitable for many programmers to develop large-scale software together. It has a long development cycle and supports cloud computing network services. The Go language allows programmers to develop quickly, and as the software continues to grow, it makes it easier for programmers to maintain and modify it. It combines the efficiency of traditional compiled languages ​​with the ease of use and expressiveness of scripting languages.

As a server programming language, Go language is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, database agents, etc.; in terms of network programming, Go language is widely used in Web applications and API applications. , download applications, etc.; in addition, the Go language can also be used in the field of memory databases and cloud platforms. Currently, many foreign cloud platforms are developed using Go.
