Learn Basic JavaScript by Building a Role Playing Game - Step 65

Help I’m not sure where I’m screwing up. I tried entering the below code and it’s not working. I’m sure it’s a simple error in my part. I’m just not seeing it.

Your code so far

I would suggest resetting the lesson.

So location["button text"] is an array.
When you want to access elements from an array you use bracket notation and pass in the index number of the element you need to access.

Here is an example of accessing the second element in the array by passing in the index 1 since arrays are zero based indexed.

for example

const exampleArr = ["example text 1",  "example text 2"];

exampleArr[1] // returns "example text 2",

For this lesson you need to keep the location["button text"] already there.
Instead you need to add to it by using bracket notation to get the first element in the array

hope that helps

I tried that but it does not work. I’m stuck on this one as well. I did:

button1.innerText = location[“button text”[0]];

which does not work.

That’s very close. To access the first element of an array is array[0], right?

The array is location[“button text”]

You access the first element of “button text”, not location[“button text”]

location[“button text”] = [1, 2, 3]

How would you access the first element of this array?

Thank you so much for your help! It worked!

HI @jp0542074 !

You are not passing because of errors.
The [0] does not go inside location['button text']
location["button text"] is an array. So the brackets need to be next to it
