Let/var/const

Not sure your use of these is totally consistent.

Here you use let for variables that don't seem to ever be re-assigned, and in the same file you also use var and const. As far as I can see everything in that file could be a const.

Not a big deal and probably won't break anything but why not be consistent :)
