1. Google Go
Go, also known as golang, was launched in 2009, having been created by three Google employees - Robert Griesemer, Rob Pike, and Ken Thompson - in 2009.
The open source language is viewed as faster and easier to use than more established languages such as Java and C, from which it is derived.
It is used by a number of organisations, from the BBC to SoundCloud, and Facebook to the UK government award-winning GOV.UK site. It is also used by enterprise software startup du jour, Docker.
“Go is an attempt to combine the ease of programming of an interpreted, dynamically typed language with the efficiency and safety of a statically typed, compiled language,” its creators say.
