Error in Firefox

[dedayoa]

Hello,
humanize.js worked fine for me in chrome, but failed to work in Firefox - even the latest version. I discovered it had to do with un-initializing const before using it.

I found the causes on line 355 and line 150. By changing to let (ES6) - which is what I think it should be considering we are using the variables in a for loop, it resolved the problem.
