Go Language Introduction

The go language is the second open source programming language that Google released in 2009. Go language Features: quasi-programming of multi-processor applications is optimized, using the Go compiler can be comparable to C or C + + code speed, but also has the Python interpretation of the language concise and development efficiency.

The following paragraph is taken from the knowledge: (including your own modifications)

Benefits of Go:

Can be compiled into machine code, not dependent on other libraries

Static type language, with a sense of dynamic language. Static language is can be compiled at the time to check out the most hidden problems, dynamic language feeling is that a lot of packages can be used, write up a high efficiency

The language level supports concurrency, which is the biggest feature of the go language, innate support for concurrency (innate genes and subsequent cosmetic surgery are differentiated)

Built-in runtime, supports garbage collection mechanism

Easy to learn, C-language gene, go language has 25 keywords, but very strong expression ability

Rich Standard library, built-in large library, especially network library is very powerful

Built-in powerful tools to make review simple, so that the code format is identical

Cross-platform compilation, can not rely on the system information

Built-in C support

Go fit:

Server programming

Distributed system, database agent

Network programming

Cloud Platform, the domestic seven Qiniu storage key service is to use the Go language development

The downside of Go:

Go import package does not support version, upgrade is easy to cause the project is not operational, so you need to control the corresponding version information

Go Gotoutine once started, the different goroutine switch between the program control, runtime scheduling, the need for rigorous logic, otherwise goroutine sleep, over a period of time logic ended, suddenly came out and executed, will lead to logic errors and other situations

The GC delay is a bit large
