/**
 * TASK 1 - Create a basic calculator
 *
 * Create a function that takes 3 arguments: operator, operand1, operand2
 * operator can be "add" "subtract" "multiply" or "divide"
 * return the result of the operation on the operands
 * return null if the operator argument is not one of the 4
 * no other errors or exceptions need to be handled
 * use a switch statement to choose the right operator
 *
 * @param {String} operator The type of operation "add" ... etc.
 * @param {Integer} operand1
 * @param {Integer} operand2
 */
function calculator


/*
 * TASK 2a - Throw an error
 *
 * Improve your calculator by testing for divide by zero and throw exception
 * In the case that the 2nd operand is zero, throw a new Error and give it a 
 * reasonable message.
 *  
 * @param {String} operator The type of operation "add" ... etc.
 * @param {Integer} operand1
 * @param {Integer} operand2
 */
function calculatorWithZero


/* 
 * TASK 2b - Catch an error
 * Write a function usecalculator() that invokes your calculator function
 * 5 times.  For the first 4, demonstrate that your calculator does the 4
 * operations. For the fifth, try to divide by zero and catch the resulting 
 * exception.  All your test cases should be within the try statement.
 * When values are returned from the calculator function, merely print them
 * to the console.log().
 */
function useCalculator() ...


/*
 * TASK 3 - Variable number of arguments
 * 
 * Create a sum function that will take a variable number of parameters and
 * return their sum
 *
 * @param {...number} var_args Any random number of variables.
 */
function sum...


/*
 * TASK 4 - Objects and methods
 * 
 * Create a counter, as a literal object, that starts a count at zero and has
 * methods increment, report, and reset (to zero).
 * report should print the current count to console.log
 */
var counter = { ...



/*
 * TASK 5 - Synthetic events
 * 
 * Create two events, pingEvent and pongEvent
 * Each event handler should:
 *  alert(e.message) where the message is "Ping" or "Pong"
 *  then setTimeout for 1500ms to dispatch the other event
 *  do this up to 3 times, then don't dispatch any longer
