Go compiles directly into machine code. The compilation is fast, cross-platform compatible and it creates only one executable file without dependencies.
It is safe, as it uses strong and static typing. Also, garbage would be collected automatically and you can make really reliable software using Go.
It supports some kinds of object-oriented programming (OOP) and interfaces.
You can attach functions to any type. That's real flexibility.
Also, Golang supports functional programming features like anonymous functions, closueres and first-class functions.
Common utilities like HTTP fetching, JSON parsing and encryption are included by default in Go in the form of standard libraries.
Go has great built-in command-line tools (ex. auto-formatting your code, test coverage reporting, refactoring tools).
