  ### 4. Now call the function you wrote in Question 3 using a variable or constant instead of a string literal. What do you expect to see in the console? Try passing in a _variable_ you declared (using `var`) as an argument. Then change that variable's value and call your function again. What do you see in the console?

  ### 5. Write your own function in which you declare a _variable_ (of any type) inside the function's body. Print out this variable to the console from within your function. After you print the variable once, assign a new value to this variable on the next line. Print it again (after the line on which you assign it to a new value). Call your function several times. What do you expect to see printed to the playground's console each time you call this function?
