Objects are similar to arrays, except that instead of using indexes to access and modify their data, you access the data in objects through what are called properties.
Here's a sample object:
var cat = {
"name": "Whiskers",
"legs": 4,
"tails": 1,
"enemies": ["Water", "Dogs"]
};
Objects are useful for storing data in a structured way, and can represents real world objects, like a cats.
