In FireFox after completing this module and running I am presented with this error:

[cannot use the given object as a weak map key]

It works in Chrome so it's not a big deal. I jsut wasted an hour checking my work when it didn't work in FireFox. I saw someone online report that they had the same problem so it doens't seem I am alone. I just wanted to report it so whoever creates the TrailHead modules can look into and correct it if needed.
