Golang is a language made by Google back in 2009. It's widely used internally and outside. 2 years ago I built a large project using it. Now that I am working on it again, I've realized a few things.

Features

What you'll read everywhere is that:

it compiles extremely fast.
it is made for multi-threading. They are called subroutines, are much lighter-weight than regular threads, and much safer to use.
it is more readable and less prone to error than C.
it is cross-platform. It can compile and run on Linux, Mac and Windows.
it is easy to learn. It has much fewer keywords and constructs than other languages.

Thoughts

It does deliver on the promise of fast compilation and being cross-platform.

I am not so sure about being easy to learn. Its syntax is completely different from other languages. Since it is made to be simple, it also misses libraries that I would have expected to be there. Here's a list of basic things I have a hard time remembering.

Checking if a map contains an element:

if _, ok := dict["foo"]; ok {
    // Do something.
}
