# --description--
|
|
|
|
Use an `else` statement to run when the `inventory` length is not more than one. Set the `text.innerText` to say `Don't sell your only weapon!`.
|
|
|
|
# --hints--
|
|
|
|
Your `sellWeapon` function should have an `else` statement.
|
|
|
|
```js
|
|
assert.match(sellWeapon.toString(), /else/);
|
|
```
|
|
|
|
You should set `text.innerText` to `Don't sell your only weapon!`.
|
|
|
|
```js
|
|
assert.match(sellWeapon.toString(), /text\.innerText\s*=\s*('|")Don't sell your only weapon!\1/);
|
|
```
|
|
|
|
Your new `text.innerText` line should be in your `else` statement.
|
|
|
|
```js
|
|
inventory = ["Naomi"];
|
|
sellWeapon();
|
|
assert.equal(text.innerText, "Don't sell your only weapon!");
|
|
```
