The best way to think about Go is to think about all the things that it doesn't have.

• Go doesn’t have a virtual machine or an LLVM-based compiler.
• Go doesn’t have exceptions.
• Go doesn’t have user-defined implementation inheritance.
• Go doesn’t have overloading for functions, methods, or operators.
• Go doesn’t have immutables.
• Go doesn’t have enumerations.
• Go doesn’t have generics.
• And Go hasn’t added any major features since Go 1 was released in 2012.

The one exciting thing that Go has is built-in concurrency support via goroutines, channels, and select. However, it is based on ideas from CSP, communicating sequential processes, which was first described in 1978.
