1. 1 point: Write a statement to create an untyped object and assign it to the variable a.

    a = {};

  2. 1 point: Set the name property of your untyped object to 'Brad'.

    a.name = 'Brad';

  3. 3 points: Write a function that takes an array of numbers as a parameter and returns its minimum value. You may either use the sort function with an appropriate comparision function or you may search the array. You may assume that the array has at least one element. 

         function min(num_array) {
       min = num_array[0];
       for (i in num_array) {
         if (num_array[i] < min) 
	    min = num_array[i];
       }
       return min
     }
