Title: Throw Errors instead of logging to console

Not all browsers have `console` defined. Also, both of these cases
where you logged to the console were cases where the user was
potentially using the library incorrectly. Throwing errors will
alert the user immediately that they are doing something wrong, and
will provide them with the means to fix the problem.
