Learn Basic JavaScript by Building a Role Playing Game - Step 59

I have my js code here and I dont know whats wrong, I followed youtube tutorial and it still error, here is my error message : " You should not modify the first locations object."

Js code:

let xp = 0;
let health = 100;
let gold = 50;
let currentWeapon = 0;
let fighting;
let monsterHealth;
let inventory = ["stick"];

const button1 = document.querySelector('#button1');
const button2 = document.querySelector("#button2");
const button3 = document.querySelector("#button3");
const text = document.querySelector("#text");
const xpText = document.querySelector("#xpText");
const healthText = document.querySelector("#healthText");
const goldText = document.querySelector("#goldText");
const monsterStats = document.querySelector("#monsterStats");
const monsterName = document.querySelector("#monsterName");
const monsterHealthText = document.querySelector("#monsterHealth");
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."
  },
];


// initialize buttons
button1.onclick = goStore;
button2.onclick = goCave;
button3.onclick = fightDragon;

function update(location) {

}

function goTown() {
  button1.innerText = "Go to store";
  button2.innerText = "Go to cave";
  button3.innerText = "Fight dragon";
  button1.onclick = goStore;
  button2.onclick = goCave;
  button3.onclick = fightDragon;
  text.innerText = "You are in the town square. You see a sign that says \"Store\".";
}

function goStore() {
  button1.innerText = "Buy 10 health (10 gold)";
  button2.innerText = "Buy weapon (30 gold)";
  button3.innerText = "Go to town square";
  button1.onclick = buyHealth;
  button2.onclick = buyWeapon;
  button3.onclick = goTown;
  text.innerText = "You enter the store.";
}

function goCave() {
  console.log("Going to cave.");
}

function fightDragon() {
  console.log("Fighting dragon.");
}

function buyHealth() {

}

function buyWeapon() {

}

Please post the link to the Step. Hard to say more without that.

This means you made changes that weren’t requested by the instructions. I’d reset the code and only make the changes the step talks about.
