Learn Basic JavaScript by Building a Role Playing Game - Step 85

What am I doing wrong here?

# Step 85

The value of the currentWeapon variable corresponds to an index in the weapons array. The player starts with a stick, since currentWeapon starts at 0 and weapons[0] is the stick weapon.Preformatted text

In the buyWeapon function, use compound assignment to add 1 to currentWeapon - the user is buying the next weapon in the weapons array.

Your code so far

function buyWeapon() {
  if (gold >= 30) {
    gold -= 30;

Hello. In this challenge, you are to use compound assignment to add 1 to the value of currentWeapon.

And if you don’t value what compound assignment is it’s basically this:

let myValue = 3;
myValue += 1; 

which is another way of saying

let myValue = 3;
myValue = myValue + 1;

This part isn’t so important but it can also be expressed as the following your incremental assigment:

let myValue = 3;

More on compound assignment.

Happy learning. :slight_smile:


The right code would be this:

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
