 Now try invoking the function `prompt` with a string input of `"What is your name?"` - store the return value of your call to `prompt` in an variable called `myName`.
 
 What effect does calling the `prompt` function have?
+Answer: It creates a pop up window which allows the user to input data. This prompt has a cancel and an 'OK' button.
 What is the return value of `prompt`?
+Answer: The return value will depend on what the user inputs. If the user presses the 'cancel' button, then the return is null. If the user presses 'OK' without entering anything, then the return type is an empty string. Else if something is written by the user, then the return value will be what the user has entered.
