I may be wrong, but I don't think this is technically true. I don't think Elm has only total functions, but it does avoid a lot of common, error-prone partial functions (e.g. accessing elements from a collection).

I am not following Elm closely and may be wrong, but I'd be surprised. The creator (Evan) is really picky about having unsafe features in the language.

It's even impossible to upload a package to the official repository containing JavaScript code without prior approval, because the native code may crash!
