# --description--
|
|
|
|
If the player has purchased all of the weapons in the inventory, the player should not be able to purchase any more and a message should be displayed.
|
|
|
|
Add an `else` statement for your outer `if` statement. Inside this new `else` statement, set `text.innerText` to `"You already have the most powerful weapon!"`.
|
|
|
|
Test your `buyWeapon` function again to make sure the message is displayed when the player has the most powerful weapon.
|
|
|
|
# --hints--
|
|
|
|
You should have another `else` statement in your `buyWeapon` function.
|
|
|
|
```js
|
|
const matches = buyWeapon.toString().match(/else/g);
|
|
assert.equal(matches.length, 2);
|
|
```
|
|
|
|
You should set `text.innerText` to `"You already have the most powerful weapon!"`.
|
|
|
|
```js
|
|
assert.match(buyWeapon.toString(), /('|")You already have the most powerful weapon!\1/);
|
|
```
|
|
|
|
You should modify your `text.innerText` to `"You already have the most powerful weapon!"` within your outer `else` statement.
|
|
|
|
```js
|
|
currentWeaponIndex = 5;
|
|
buyWeapon();
|
|
assert.equal(text.innerText, "You already have the most powerful weapon!");
|
|
```
