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.

assert.match(buyWeapon.toString(), /newWeapon/);

You should use let to declare newWeapon.

assert.match(code, /let\s+newWeapon/);

newWeapon should be initialised to have the value of weapons. Don't forget your semicolon.

assert.match(buyWeapon.toString(), /newWeapon\s*=\s*weapons\s*;/);

newWeapon should be declared before you modify text.

const splitBySpaces = buyWeapon.toString().split(/\s+/);
const textLocation = splitBySpaces.indexOf('text.innerText');
const newWeaponIndex = splitBySpaces.indexOf('newWeapon');
const newWeaponLocation = newWeaponIndex !== -1 ? newWeaponIndex : textLocation;
assert.isBelow(newWeaponLocation, textLocation);
