Go is certainly one of the fastest languages to learn. The introduction tour is complete within a few hours, after which you will have already encountered all of the features of the language. However, there is still a long way to go before one is ready for the routine use of the tools and concepts. Especially if you are coming from another programming language, you tend to simply “translate” known concepts to Go, which does not usually produce satisfactory results. A deeper understanding of the language and its idioms will help you to address the unique language features and ultimately allow you to write better software.
