function attack() {
  text.innerText = "The " + monsters[fighting].name + " attacks.";
text.innerText = "You attack it with your" + weapons + "."
}

I don’t understand what current weapon the player has,

Hi @masha2

You’ll need to first fix the errors regarding the second text.innerText.
Then the spacing for the second string.

When that is done, the error message will display the variable needed to display the current weapon.

Happy coding

It would be great to understand how to do this and what to do

4 
text.innerText += " You attack it with your " + weapons[currentWeapon].name + "."

If we move on to the array of weapons, then what does the current weapon have to do with it? I thought if we set the name of the array, then we can only enter inside this array, but it’s not at all clear how this works.

Hi @masha2

I’m glad you figured out how to solve the step.

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

The variable weapons is a reference to an array.
It contains all the weapons in the game.

weapons[currentWeapon].name

currentWeapon is a number, which is used to index the weapons array.
Inside the array, each item is an object.

Dot notation is used to find the name of the item.

For example:
if currentWeapon is 0.
then weapons[0] would access the object { name: 'stick', power: 5 }

then, weapons[0].name would access the string stick.

Happy coding
