Overview
Go Language Specification document defines Go as a general-purpose compiled language designed with systems programming in mind. It is statically and strongly typed and garbage-collected and has explicit support for concurrent programming. Programs are constructed from packages, whose properties allow efficient management of dependencies. The existing implementations use a traditional compile/link model to generate executable binaries.
Go declarations can be read "naturally" from left to right, which makes it easy to read.
These are several reasons to use Go:
- It compiles fast, and it runs fast
- Concurrency is a fundamental part of the language
- The standard library has almost everything one needs
- It is a terse language and "feels" dynamically typed, but it compiles straight into machine code

Type
To deplete Go Concepts - The Type System
Go is a strongly and statically typed language with no implicit conversions. This gives Go a stronger type safety than Java, which as implicit conversions, but the code reads more like Python, which has untyped variables.
Modularization
In Go, programs are constructed from packages. More details:
Object Oriented Programming
