--- id: 5d708ab5066dac7142a6d79b title: Part 73 challengeType: 0 dashedName: part-73 --- # --description-- At some point in the future, you may want to add more weapons. Instead of checking if `currentWeapon` is less than three, check if `currentWeapon` is less than the length of the `weapons` array. For example, here is how you would get the length of an array called `arr`: `arr.length`. # --hints-- See description above for instructions. ```js assert( buyWeapon .toString() .match( /if\s*\(\s*currentWeapon\s*\<\s*weapons\.length\s*\)\s*\{\s*if\s*\(\s*gold\s*\>\=\s*30\s*\)\s*\{/ ) ); ``` # --seed-- ## --before-user-code-- ```html
