Having trouble setting the function here for the callback function.. ?

There are 2 questions in the quiz that reference a callback function. One asks you to "Pass addEventListener() a reference to the handleChange function." In this question, it wants to make sure you understand that when you pass the reference to a callback function, you only put in the name of the function, and do not follow it with parentheses. The other asks you to "Set the makeMeal function to invoke the callback function passed to it." In this one, you simply call the function that is passed in. In this case, the parameter that represents the callback function is named cb, so you would simply call cb(). If the function that was passed in required a parameter, you would likely have called cb(meal), but since it is just printing an alert that doesn't require a parameter, you simply call the function without parameters.
