Updating Object Properties

After you've created a JavaScript object, you can update its properties at any time just like you would update any other variable. You can use either dot or bracket notation to update.

For example, let's look at ourDog:

var ourDog = {
"name": "Camper",
"legs": 4,
"tails": 1,
"friends": ["everything!"]

Since he's a particularly happy dog, let's change his name to "Happy Camper". Here's how we update his object's name property:

ourDog.name = "Happy Camper"; or

ourDog["name"] = "Happy Camper";

Now when we evaluate ourDog.name, instead of getting "Camper", we'll get his new name, "Happy Camper".


Update the myDog object's name property. Let's change her name from "Coder" to "Happy Coder". You can use either dot or bracket notation.
