My book is showing its age, go get has been deprecated.

go is a typed language, compiled, but builds very fast. Complexity is built up through use of interfaces and composition. Functions can return multiple values ie val, err := doSomeThing(oldVal) Doesn’t need parenthesis on conditional statements like js does. Doesn’t need end of statement semicolon’s the way js does.

goroutines for concurrency, channels to pass data funcs starting with UpperCase are exported, lowerCase are not package system
