# --description--
|
|
|
|
You can make an `else` statement conditional by using `else if`. At the end of your `if` statement, add an `else if` statement to check if `monsterHealth` is less than or equal to `0`. In your `else if`, call the `defeatMonster` function.
|
|
|
|
Here's an example:
|
|
|
|
```js
|
|
if (num > 10) {
|
|
|
|
} else if (num < 5) {
|
|
|
|
}
|
|
```
|
|
|
|
# --hints--
|
|
|
|
You should have an `else if` statement.
|
|
|
|
```js
|
|
assert.match(attack.toString(), /else if/);
|
|
```
|
|
|
|
Your `else if` statement should check if `monsterHealth` is less than or equal to `0`.
|
|
|
|
```js
|
|
assert.match(attack.toString(), /else\s*if\s*\(\s*monsterHealth\s*<=\s*0\s*\)/);
|
|
```
|
|
|
|
Your `else if` statement should call the `defeatMonster` function.
|
|
|
|
```js
|
|
assert.match(attack.toString(), /else\s*if\s*\(\s*monsterHealth\s*<=\s*0\s*\)\s*\{\s*defeatMonster/);
|
|
```
