Monday, October 18, 2010 Why 4 Why a new language? Monday, October 18, 2010 Why Go? 5 A response to Google’s internal needs: - efficient large scale programming - speed of compilation - complexity, weight, noise (C++, Java) vs. - no static checking (JavaScript, Python) Go is statically typed and compiled, like C++ or Java (with no VM), but in many ways feels as lightweight

Programming in Go is different from programming in most procedural languages. If you try to write Java* programs in Go, you may may become frustrated. If you write Go programs in Go, you will be much more productive. Our goal today is to teach you to think like a Go programmer. *Sometimes we'll use Java as a reference for

Real World Go Andrew Gerrand May 9, 2011 Background 3 Google Confidential Why Go? • Statically typed languages are efficient, but typically bureaucratic and overly complex. • Dynamic languages can simplicity: pick two.” (sometimes just one) • Can’t we do better? 3 Google Confidential What is Go? • Go is a modern, general purpose language. • Compiles to native machine code (32-bit and 64-bit x86 Concurrency primitives. 3 Google Confidential Tenets of Go’s design • Simplicity – Each language feature should be easy to understand. • Orthogonality – Go’s features should interact in predictable and consistent

The Zen of Go GopherChina 2021 How should I write good code? How do you know when you’ve written good code?
