Does Go language have any advantages?

Go language has advantages: 1. Easy learning curve; 2. High development efficiency and operating efficiency; 3. Go language can be said to be a perfect fusion of development efficiency and operating efficiency, with natural concurrent programming support; 4. The Go language has powerful compilation checks, strict coding standards and complete software life cycle tools. It has strong stability, and stability is paramount.

Advantages of Go language

1. Easy learning curve

Go language has simple syntax, including C-like syntax. Because the Go language is easy to learn, an ordinary college student can write a usable, high-performance application in a few weeks. Everyone in China pursues speed, which is one of the reasons why Go is so popular in China.

The grammatical features of Go language are simply too simple, so simple that you can hardly do any tricks. It’s straight forward and has a learning curve. It's very low and very quick to get started with.

2. Efficiency: fast compilation time, high development efficiency and running efficiency

Compared with the sluggish compilation speed of Java and C during the development process, Go’s fast compilation time is A major efficiency advantage. Go has operating efficiency close to C and development efficiency close to PHP.

The philosophy of C language is to trust programmers, keep the language small, not shield the bottom layer and be bottom-level friendly, and pay attention to the execution efficiency and performance of the language. Python's attitude is to accomplish as much as possible with as little code as possible. So I can feel that the Go language wants to unify C and Python, which is a great thing.

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

The reason why Go comes from a well-known family can be seen from the creator of the Go language. , Go language is absolutely pure. Secondly, the Go language comes from Google. It goes without saying that Google’s popularity and strength in the industry are natural. 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.

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

Go language can be said to be the development efficiency and operation The perfect fusion of efficiency and natural concurrent programming support. Go language supports all current programming paradigms, including procedural programming, object-oriented programming, interface-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. The lib library of Go language is small but has all the essentials. The lib library of the Go language basically contains the vast majority of commonly used libraries. Although some libraries are not very good, I don’t think it is a problem, because I believe these problems will be solved in future development.

6. Convenient deployment: binary files, Copy deployment

This is the biggest reason why many people choose Go. Because deployment is so convenient, many people now use Go to develop operation and maintenance programs. .

7. Simple concurrency

Parallel and asynchronous programming are almost painless. The two artifacts of Go language, Goroutine and Channel, are simply huge blessings for concurrent and asynchronous programming. The concurrency and asynchronous methods of languages ​​​​such as C, C, Java, Python and JavaScript are too complex to control and prone to errors, and Go solves this problem very elegantly and smoothly. For programmers who have suffered from concurrency and asynchronous programming for many years, this is a completely eye-catching feeling. Go is a very efficient language with high support for concurrency. Go is a programming language developed for big data, microservices, and concurrency.

• Go as a language strives to make things simple. It doesn't introduce many new concepts, but focuses on creating a simple language that is incredibly fast and easy to use. Its only innovations are goroutines and channels. Goroutines are Go's lightweight thread-oriented approach, and channels are the preferred way of communicating between goroutines.

• The cost of creating Goroutines is very low, requiring only a few thousand bytes of additional memory, which makes it possible to run hundreds or even thousands of goroutines simultaneously. Communication between goroutines can be achieved with the help of channels. Goroutines and the channel-based concurrency approach make it very easy to use all available CPU cores and handle concurrent IO. Compared to Python/Java, running a function on a goroutine requires minimal code.

8. Stability

Go has powerful compilation checks, strict coding standards and complete The software life cycle tool 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.
