Js Fatal error if tokenSeparator is not defined.

[iruzevic]

Version: 3.2.1 Browser: chrome latest Os: osx

I'm using fuse.js in my project, everything is fine when I build it in production mode using webpack. But when I run it via code optimisations and minification from Wp rocket cache plugin it breaks.

The problem occurs in the console:

SyntaxError: Invalid regular expression: /+/: Nothing to repeat

I debugged and the problem and it occures here:

tokenSeparator = _ref$tokenSeparator === undefined ? / +/g : _ref$tokenSeparator,

I have managed to fix this by adding this to my options:

tokenSeparator: '|',

Generally I think that the problem lies in the spacing in this line: "/ +/g" Optimisation plugin removes all unnecesery white spaces that are not strings inside quotes and when it does, your plugin will not work. Please check this and provide a fix, this is a nasty bug that happends in edge cases. At lease write this inside the documentation.

tnx. If you need any more code samples please ask.
