    True or False… There is no limit on the number of interfaces a class can implement.

    Really? Infinity?

    Fill in the blank. Event constants are always of type _______.

    A “const” can be of any type, including *. So not even Object is the right answer.

    there is not a set number

    >Fill in the blank. Event constants are always of type
    the question is not about const… but Event constants … implying that they are to be used with the first argument of addEventListener… with the first argument of the Event constructor etc… therefore Object is not a valid answer
