# --description--
|
|
|
|
Your `locations` array doesn't have a fifth element, so `locations[4]` doesn't work.
|
|
|
|
Add a new object at the end of the `locations` array, following the same structure as the other objects. Set `name` to `"kill monster"`, set `"button text"` to an array with three `"Go to town square"` strings, set `"button functions"` to an array with three `goTown` variables, and set `text` to `"The monster screams Arg! as it dies. You gain experience points and find gold."`.
|
|
|
|
# --hints--
|
|
|
|
Your `locations` array should have five values.
|
|
|
|
```js
|
|
assert.lengthOf(locations, 5);
|
|
```
|
|
|
|
Your fifth `locations` value should be an object.
|
|
|
|
```js
|
|
assert.isObject(locations[4]);
|
|
```
|
|
|
|
Your fifth `locations` value should have a `name` property with the value `"kill monster"`.
|
|
|
|
```js
|
|
assert.equal(locations[4].name, 'kill monster');
|
|
```
|
|
|
|
Your fifth `locations` value should have a `"button text"` array with three `"Go to town square"` strings.
|
|
|
|
```js
|
|
assert.deepEqual(locations[4]["button text"], ['Go to town square', 'Go to town square', 'Go to town square']);
|
|
```
|
|
|
|
Your fifth `locations` value should have a `"button functions"` array with three `goTown` variables.
|
|
|
|
```js
|
|
assert.deepEqual(locations[4]["button functions"], [goTown, goTown, goTown]);
|
|
```
|
|
|
|
Your fifth `locations` value should have a `text` property with the value `"The monster screams Arg! as it dies. You gain experience points and find gold."`.
|
|
|
|
```js
|
|
assert.equal(locations[4].text, 'The monster screams Arg! as it dies. You gain experience points and find gold.');
|
|
```
