Yes, but sometimes it is much easier to get moving with a good textbook.
With Go, a few online tutorials and the documentation that comes with Go itself, were all I needed to get going. I am not sure if that was an explicit design goal, but I found the language very easy to learn.
I believe it was an explicit design goal. They wanted new employees joining from straight out of college to be effective within Google's codebase as soon as possible. Therefore the learning curve is pretty low if you already know another mainstream programming language.
This applies to almost all languages and technologies!
