//*****************************************************
// Three ways to create an array
//*****************************************************
//1. Literal Array
var myfruits = ["apples", "bananas", "canalope"]; //literal
//2. Condensed Array
var myColors = new Array("red", "green", "blue"); // condensed array
//3. Regular Array - you can add an optional number when defining array to control arrays
// size
var myAnimals = new Array(); // regular array (add an optional integer
myAnimals[0] = "Loins"; // argument to control array's size)
myAnimals[1] = "Tigers";
myAnimals[2] = "Bears";
//*****************************************************
// Two Ways to Access an array
//*****************************************************
//1. Access the entire array
document.write(myfruits);
document.write("<br />");
//2. Access an element
document.write(myColors[1]);
document.write("<br />");
//******************************************************
