Now your `update` function needs to use the argument you pass into it. Inside the `update` function, change the `button1.innerText` assignment to be `location["button text"]`. That uses bracket notation to get the `button text` property of the `location` object passed into the function.

# --hints--
|
||
|
|
|
||
|
|
Your `update` function should use bracket notation to get the `button text` property of the `location` object passed into the function.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.match(update.toString(), /location[('|")button text\1]/);
|
||
|
|
```
|
||
|
|
|
||
|
|
You should assign the value of the `button text` property of the `location` object to the `innerText` property of `button1`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert.match(update.toString(), /button1\.innerText\s*=\s*location\[('|")button text\1\]/);
|
||
|
|
```
