Fixes #429 - support .js views with functions.

[JEStaubach]

Allows functions to be passed in views by allowing javascript files instead of only JSON files.

Thanks a lot for this contribution! 💯

Any plans or thoughts for testing this? It's important we know this works as expected, both currently and going forward when doing future improvements.

I should be able to make that happen. Since #429 referenced having an issue with the bold example in the readme section that sounds like a good test to start with.

Great getting a test in place 👍 Other than a naming nitpick, this LGTM.

Published in v3.1.0.

Hi @JEStaubach!
I'm a newcomer to mustache and to development in general. I managed importing my JSON as js, including it into a variable. But...

Does that changes the way entries should be passed to Mustache? I included my json in a variable, but it seems now mustache doesn't find the array where values are stored to be substituted in the template. I tried doing

{{#variable.arrayName}}
{{item}}
{{/variable.arrayName}}

But that didn't work.

Thank you!!
