# --description--
You should tell the player what weapon they bought. In between the two lines you just wrote, use `let` to initialize a new variable called `newWeapon`. Set this to equal `weapons`.
# --hints--
Your `buyWeapon` function should have a variable named `newWeapon`.
```js
assert.match(buyWeapon.toString(), /newWeapon/);
```
You should use `let` to declare `newWeapon`.
```js
assert.match(code, /let\s+newWeapon/);
```
`newWeapon` should be initialised to have the value of `weapons`. Don't forget your semi-colon.
```js
assert.match(buyWeapon.toString(), /newWeapon\s*=\s*weapons;/);
```
`newWeapon` should be declared before you modify `text`.
```js
const contents = buyWeapon.toString().split(/\s+/);
assert.isBelow(contents.indexOf('newWeapon'), contents.indexOf('text.innerText'));
```
