Tell us what’s happening:

I cannot understand how to use the logical AND operator.

### Your code so far:

if (isMonsterHit( )  &&  inventory.length !== 1) {
    monsterHealth -= weapons[currentWeapon].power + Math.floor(Math.random() * xp) + 1;    
  } else {
    text.innerText += " You miss.";
  }

This challenge is about the player’s only sword breaking. " We don’t want a player’s only weapon to break. The logical AND operator checks if two statements are true.

Use the logical AND operator && to add a second condition to your if statement. The player’s weapon should only break if inventory.length does not equal (!==) one."

But you do have a good example of an logical AND operator.

Happy learning. :slight_smile:

Here is an example of the logical AND operator.

if (firstName === "Quincy" && lastName === "Larson") {

}

It allows us to use multiple conditions in an if statement.

And as for where the code is supposed to be used.

We want to use it in the code block where the player’s weapon breaks.

Can u tell me what you mean by applying the code to the wrong destination, i tried to solve this but still didn’t work. So far my code:

if(weapons.length > 1 && inventory.length > 1){ }

You don’t need to create a new function but add second function using logical And operator. Add second function using (&&) operator in the already present weapon break if condition you already wrote in step 154.
