There's was an overlooked behavior inconsistency between the assignment of this.state.currentEnthusiasm assigment at the Hello component constructor and the expect behavior in the test 'throws when the enthusiasm level is 0'.
I fixed the assignment rather than the test itself so that the wanted behavior will work. When enthusiamLevel is 0 it will now actually throw and error instead of bypassing the falsy value and setting this.state.currentEnthusiasm to 1.
