The Go programming language is an open source project to make programmers more productive. Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. @LucaMarzi, Once you've absorbed this, the next thing to think through is that values of types which are pointers or contain pointer fields may form arbitrary hierarchies (a tree containing maps in its leaves is a silly but simple example), and how to deep-copy a value of a particular type is an open question which cannot have one "true" answer. To illustrate, let's …Gotcha 1 - Array != Slice. An experienced gopher knows this by the hearth, but if you are a developer who jumps between languages depending on the project, it may get confusing.
