So it's safe to say by now that when you use the "prompt" method in javascript, it automatically stores the input value?

I don't know if this was explained in a prior video, but it's important to note that you don't need a variable to store an input value when you have prompt, correct?

Thanks

You need a variable to store an input when you have a prompt box. Otherwise the value is forever lost.

prompt("How many days are in a week?");

(The user types 7 and the number is not stored anywhere. You can't access this value and you can't use it later in your code.)

var weekDays = prompt("How many days are in a week?);

(The user types 7 and the number is stored in the weekDays variable. You can access its value and use it later in your code.)

If you wish to use the input and recall it from memory then you'll need a variable to store it in or else you will have no way of accessing the data from memory to my knowledge.
