Possible Implementation

I'm going to investigate this bug and reply to this issue if I find a fix / open a PR.

The issue seems to come from the string that is passed to the camelCase() function. It seems that the '/' in the input string gets removed and replaced by a whitespace.

So the function ends up calling .toUppercase() on a whitespace.

I have the same issue: green ( opted out ) converts to green opted with double space.
