Role Playing Game - Step 85 (Help me with the logic)

Tell us what’s happening:

Nothing is happening. I’m actually going through this course again because I didn’t understand most of it. Some of the concepts weren’t defined or explained, like the upgrade() function having a paramater that closely matched the variable with an array of information related to the paramater’s name.

This one however I truly can’t understand. The instructions claim the variable currentWeapoon is linked to the const weapon array. HOW? How does the currentWeapon value of 0 indicate it is linked to the weapons array? Shouldn’t the code be: let currentWeapon = weapons [0]; instead?

I just need to understand the logic. Thanks in advance.

Your code so far

let currentWeapon = 0;


const weapons = [
{ name: ‘stick’, power: 5 },
{ name: ‘dagger’, power: 30 },
{ name: ‘claw hammer’, power: 50 },
{ name: ‘sword’, power: 100 }
];


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

Depending on the actual number currentWeapon is, it can indicate different weapons - weapons[currentWeapon]. currentWeapon doesn’t directly point to the weapon object, but using it as index with the weapons array allows obtaining the current weapon.
