Here is a list of various things I love about the Go programming language:

Statically typed language

C-like syntax (and consistent one!)

Compiled language (No possible source code alteration when deployed on production servers)

Statically linked binaries (No dependencies hell, easy to deploy in production)

Easy cross-compilation, both 32-bit and 64-bit (FreeBSD, Linux, Mac OS X and Windows)

Ultra fast compilation

No Makefiles (Replaced by the Go tool: go build & go install)

Gofmt tool (automatically formats Go programs)

Functions with multiple return values

Rich and feature-full standard library
