Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language. Three things that make Go fast, fun, and productive: interfaces, reflection, and concurrency. 1. Code that grows with grace: One of Go's key design goals is code adaptability; that it should be easy to take a simple design and build upon it in a clean and natural way. 2. Go Concurrency Patterns: Concurrency is the key to designing high performance network services. Go's concurrency primitives (goroutines and channels) provide a simple and efficient means of expressing concurrent execution. 3. Advanced Go Concurrency Patterns
