## Description
|
||
|
|
<section id='description'>
|
||
|
|
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 <code>ourDog</code>:
|
||
|
|
<blockquote>var ourDog = {<br> "name": "Camper",<br> "legs": 4,<br> "tails": 1,<br> "friends": ["everything!"]<br>};</blockquote>
|
||
|
|
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:
|
||
|
|
<code>ourDog.name = "Happy Camper";</code> or
|
||
|
|
<code>ourDog["name"] = "Happy Camper";</code>
|
||
|
|
Now when we evaluate <code>ourDog.name</code>, instead of getting "Camper", we'll get his new name, "Happy Camper".

## Instructions

<section id='instructions'>

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

testString: 'assert(/happy coder/gi.test(myDog.name), "Update <code>myDog</code>'s <code>"name"</code> property to equal "Happy Coder".");'
|
||
|
|
- text: Do not edit the <code>myDog</code> definition
|
||
|

testString: 'assert(/"name": "Coder"/.test(code), "Do not edit the <code>myDog</code> definition");'
