Hi, welcome to the forum!
We see you have posted some code but did you have a question?

(You have not filled out the “Tell us what’s happening:” field above)

myFunction(arg[0]);

update is the function
locations is your argument.

Modify the update(locations); line and don’t add the second line

locations(arg[0]); Delete this line

Hey,

this is the step:
The locations array contains two locations: the town square and the store. Currently you are passing that entire array into the update function.

Pass in only the first element of the locations array by adding [0] at the end of the variable. For example: myFunction(arg[0]);.

This is called bracket notation. Values in an array are accessed by index. Indices are numerical values and start at 0 - this is called zero-based indexing. arg[0] would be the first element in the arg array…

and I’m not getting it what to do?

function goTown() {
  update(locations),
  locations(town square[0], store[1]);
}

locations is an array. This means it is a collection of elements.

In this case, locations contains 2 elements “town square” and “store”.

To access the “town square”, or first element, you would use this: locations[0]

console.log(locations[0]); would print “town square” to the console.

Edit this line: update(locations), it’s almost correct you just need to add 1 thing!

Instead of passing the locations array to the update() function, pass only the first element to the update() function.

locations(town square[0], store[1]);

You may delete this line.

It worked thank you for your help

Hi, i have tried the solution

function update(locations[0])

but still does not work, tho the locations word is greyed out like it has’nt been assigned anywhere, but i created the variable in the earlier steps…

const locations = [
{
name: “town square”,
“button text”: [“Go to store”, “Go to cave”, “Fight dragon”],
“button functions”: [goStore, goCave, fightDragon],
text: “You are in the town square. You see a sign that says "Store".”
},
{
name: “store”,
“button text”: [“Buy 10 health (10 gold)”, “Buy weapon (30 gold)”, “Go to town square”],
“button functions”: [buyHealth, buyWeapon, goTown],
text: “You enter the store.”
}
];

HELP PLEASE!!

hello simon79, I haven’t figured it out yet. did you get a chance to solve it?

I was trying to change the function itself instead of the button.innerText!

Hello Simon79,
I figured it. after carefully reading the instruction I found out that we only need to change the value of the assigned button1.innerText.
Hope this helps.
