Creating an Array
Using an array literal is the easiest way to create a JavaScript Array.
Syntax:
var array_name = [item1, item2, ...];
Looping Array Elements
The safest way to loop through an array, is using a for loop:
var myObj, i, x = "";
myObj = {
"name":"John",
"age":30,
"cars":[ "Ford", "BMW", "Fiat" ]
};
for (i = 0; i < myObj.cars.length; i++) {
x += myObj.cars[i] + "<br>";
}
