What are the advantages of golang?

● Simple deployment

Go compilation generates a static executable file with no other external dependencies except glibc. This makes deployment extremely convenient: only a basic system and necessary management and monitoring tools are needed on the target machine, and there is no need to worry about the dependencies of various packages and libraries required by the application, greatly reducing the burden of maintenance. It can be directly compiled into machine code and does not rely on other libraries. The version of glibc has certain requirements. Deployment is completed by throwing a file up.

● Good concurrency

Good concurrency. Goroutine and channel make it very easy to write high-concurrency server-side software. In many cases, there is no need to consider the lock mechanism and the various problems caused by it. A single Go application can also effectively utilize multiple CPU cores and achieve good parallel execution performance.

● Good language design

Good language design. From an academic point of view, the Go language is actually very mediocre and does not support many advanced language features; but from an engineering point of view, the design of Go is very excellent: the specification is simple and flexible enough, and programmers with other language foundations can quickly get started. . More importantly, Go comes with a complete tool chain, which greatly improves the consistency of team collaboration. For example, gofmt automatically formats Go code, which largely eliminates the problem of inconsistent formatting styles of codes written by different people. Configure the editor to automatically run gofmt when editing the archive, so that you can place it anywhere when writing code, and it will automatically become correctly formatted code when archiving. In addition, there are very useful tools such as gofix and govet.

● Good execution performance

Good execution performance. Although not as good as C and Java, it is usually an order of magnitude higher than native Python applications and is suitable for writing some bottleneck services. The memory usage is also very economical.
