## Testing Objects for Properties
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
Heres the example:
```javascript
// Setup
var myObj = {
gift: "pony",
pet: "kitten",
bed: "sleigh"
};
function checkObj(checkProp) {
// Your Code Here
return "Change Me!";
}
// Test your code by modifying these values
checkObj("gift");
```
Heres a solution:
We do not change anything here:
```javascript
// Setup
var myObj = {
gift: "pony",
pet: "kitten",
bed: "sleigh"
};
```
further, in the body of the function we use `.hasOwnProperty(propname)` method of objects to determine if that object has the given property name. `if/else` statement with Boolean Values will help us in this:
```javascript
function checkObj(checkProp) {
// Your Code Here
if (myObj.hasOwnProperty(checkProp) == true) {
return myObj[checkProp];
}
else {
```
and change the value of `return` in `else` statement:
```javascript
return "Not Found"
}
}
```
Now, you can change `checkObj` values:
```javascript
// Test your code by modifying these values
checkObj("gift");
```
Heres a full solution:
```javascript
function checkObj(checkProp) {
// Your Code Here
if (myObj.hasOwnProperty(checkProp) == true) {
return myObj[checkProp];
}
else {
return "Not Found"
}
}
// Test your code by modifying these values
checkObj("gift");
```
