The Go Programming Language Introducing Go. How to Build Scalable and Reliable Programs.In September 2007, Google started to internally compile multi-threaded programming language called Go which is often referred to as Golang. Three software designers namely Robert Grizmer, Rob Pike and Ken Thompson, who were previously working together at Inferno systems development projects, came together to design Golang. OpenBSD, Plan 9, Solaris, Anroid Linux MacOS, Dragonfly BSD and a few other operating systems were developed by Golang Creators. The idea of developing Golang was to have high-performance programs to run on modern distributed systems together with multi-core processors. Go was designed to help solve most of the real-world challenges when using Google to develop software. There are a number of problems to be solved with some of them being high cost of updates, uncontrollable dependencies, development duplication, slow build on programs and many more. In this book, we aim to gather some of the basic facts you need to know about Golang. Our team has compiled every possible small detail or procedure about Golang and we are excited to share with you in the following but not limited topics: History of language and its necessity Comparison with other languages; Performance, Speed & Convenience Basic language description; Syntax, Type, Design, Interface System, Syntactic Features Features of work in the GO Companies actively using GO; GO development examples Spread and prospects Development tools Examples of using program; GO rating Download your copy of " The Go Programming Language " by scrolling up and clicking "Buy Now With 1-Click" button.
