(The advantage of go language is that it can be directly compiled into machine code without relying on other libraries. Glibc version has certain requirements. Deploy by throwing a file on it. Statically typed language, but it has the feeling of dynamic language. Statically typed languages can detect most hidden problems at compile time. The feeling of dynamic language is that there are many packages that can be used, and the writing efficiency is very high. Concurrency is supported at the language level. This is the biggest feature of go, which naturally supports concurrency. Go is a concurrency supported by genes. It can make full use of multi-core and easy to use concurrency.)
