I believe parent comment was probably alluding to compilation time. My experience with Go is that the compile times are usually close to zero seconds and this indeed makes it feel almost exactly like working with Python or JavaScript.

Parent may also have been thinking of Go's concision, which feels more like using a scripting language than using a class-based monstrosity like Java, and certain other features, such as type inference that make variable declaration as painless as weakly typed languages.
