How do I remove $ sign from string using replace?

Question

I cannot remove the dollar sign from the balance properties, I am not sure what I am missing? I thought it was string.replace(searchvalue, newvalue)??

const data = [{
    index: "14",
    name: "Bob",
    balance: "$100",
  },
  {
    index: "23",
    name: "John",
    balance: "$120",
  },
  {
    index: "17",
    name: "Steve",
    balance: "$80",
  },
];

const balances = data.map((amount) => {
  var newAmount = amount.replace("$", "");
  console.log(newAmount);
});

What I want:

100
120
80

You just forgot to get the balance property of each item.

const data = [{
    index: "14",
    name: "Bob",
    balance: "$100",
  },
  {
    index: "23",
    name: "John",
    balance: "$120",
  },
  {
    index: "17",
    name: "Steve",
    balance: "$80",
  },
];

data.forEach((item) => {
  var newAmount = item.balance.replace("$", "");
  console.log(newAmount);
});

const data = [{
    index: "14",
    name: "Bob",
    balance: "$100",
  },
  {
    index: "23",

check the following code

const data = [{
    index: "14",
    name: "Bob",
    balance: "$100",
  },
  {
    index: "23",
    name: "John",
    balance: "$120",
  },
  {
    index: "17",
    name: "Steve",
    balance: "$80",
  },
];
const modifiedData = data.map((amount) => {
const oldBalance=amount.balance;// here we cache old value
 amount.balance=oldBalance.replace("$", "");// here we assign the modified value
console.log(amount.balance);

return amount;
});

console.log(modifiedData);

Please work with this code snippet. I hope this code works well with you.

const balances = data.map((amount) => {
    const newAmount = amount[balance].replace("$", "");
    console.log(newAmount)
})
