As Moore’s Law is reaching the end of its lifecycle, the need for concurrency is rising and consequently, the need for a programming language that enables effective implementation of concurrent programs is rising too. For this reason, Go has become one of the most popular languages in recent times. This course aims to provide a detailed introduction to Go for beginners. Furthermore, it also articulates how Go is different from traditional programming languages that programmers are accustomed to in order to acquaint programmers getting ready to delve into Go with the language too.

An Introduction to Programming in Go

### Returning an Error Message

In the previous lessons, we learned how to implement interfaces in Go. We will now look at how we can display error messages within them. An __error__ is anything that can describe itself as an error string. The idea is captured by the predefined, built-in interface type, error, with its single method, `Error`, returning a string:
