I use Go because ;

Simplicity or Keeping Life Simple : Go is good for any software project with any complexity - it is extremely “simple” (this is a controversial word amongst programmers). But really it is very simple, while writing go code you feel like you are writing some practical code.

Networking: Go is unusually good for writing networking applications - writing highly scalable TCP or HTTP server

Concurrency: Go is an excellent choice for concurrency - channels and goroutines make life extremely simple to understand

Learning Curve: As I mentioned simplicity GoLang is very sample syntax and easy to learn.

Dependencies: There is no dependency on the system. It works on Mac/Linux/Windows
