Tell us what’s happening:

I am not doing as I’ve been asked to add the new value in the array on inventory with the push method. I’ll really appreciate your help with that If possible.

Your code so far

/*

Read the error message more carefully here

You should push the value of newWeapon to the inventory array.

right now you are pushing "dagger" which is incorrect

you should not hardcode a value

you should use the variable they say to in the error message

then the test will pass

hope that helps

Let me try. Just one thing can you tell me what should i be writing here as

inventory.push( );
I mean in between the paranthesis. This is my first ever learning module and I got a bit confused about the whole code as it’s kept on incrementing

4

You’re issue is this part specifically

but the directions say to push the value of newWeapon

once you fix that issue, then it will pass

5

Another way to think about it is this way.

The goal of the buy weapon function is to buy a weapon and add that new weapon to your inventory.

It would make sense to add that new weapon to your inventory.

But it wouldn’t make sense to add a "dagger" each time would it?

What if the player didn’t buy a "dagger" ?
What if they bought a sword or something else?

You want to be able to dynamically add that new weapon and account for whatever the player buys.

Not hardcode a value like "dagger" because the player might not buy that

hope that makes sense

I am stuck here: Step 39

Comments allow you to add notes to your code. In JavaScript, single-line comments can be written with // and multi-line comments can be written with /* and */ . For example, here are single and multi-line comments that say “Hello World”:

// hello world

/*

hello world

*/

Add a single-line comment that says initialize buttons .

How do I Add a single-line comment that says initialize buttons to my code? I am working on the “Role playing Game.” I am in step 39. Thanks

// initialize buttons
you can write your code here instead of my sentence in this very line. Hope it helps
