One point that makes this particularly nice is the fact that for many languages of the compiled c++/Rust/etc kind there is a certain level of barrier for people coming from dynamic languages, and that is the non-existence of a repl where you can just try out basic idioms and constructs without having to manually set up a context. This kind of interactive environment kind of replaces that and therefore opens the language for much more people.
