1. Write a function to multiply each element in an array by some value. The function must have this header:

   function multiply(list, multiplier) 

   If the multiply function were called like this:

   var list = [ 17, 8, 9, 5, 20 ];var products = multiply(list, 3); 

   The multiply function would return an array with these values: [ 51, 24, 27, 15, 60 ]
