Tell us what’s happening:

This code should work. I’ve refreshed and reposted this code and am still failing test 21. And help is appreciated.

Your code so far

class BankAccount {
  constructor(balance = 0, transactions = []) {
    this.balance = balance;
    this.transactions = transactions;
  }

  deposit(amount) {
    if (amount <= 0) {
      return "Deposit amount must be greater than zero.";
    }
    this.transactions.push({ type: "deposit", amount: amount });
    this.balance += amount;
    return `Successfully deposited $${amount}. New balance: $${this.balance}`;
  }

  withdraw(amount) {
    if (amount <= 0 || amount > this.balance) {
      return "Insufficient balance or invalid amount.";
    }
    // Store withdrawals as positive amounts with type "withdrawal"
    this.transactions.push({ type: "withdrawal", amount: amount });
    this.balance -= amount;
    return `Successfully withdrew $${amount}. New balance: $${this.balance}`;
  }

  checkBalance() {
    return `Current balance: $${this.balance}`;
  }

  listAllDeposits() {
    const deposits = this.transactions
      .filter(tx => tx.type === "deposit")
      .map(tx => tx.amount);
    return "Deposits: " + deposits.join(",");
  }

  listAllWithdrawals() {
    const withdrawals = this.transactions
      .filter(tx => tx.type === "withdrawal")
      .map(tx => tx.amount); // amounts already positive
    return "Withdrawals: " + withdrawals.join(",");
  }
}

// === FreeCodeCamp Test Execution ===
let myAccount = new BankAccount();

console.log(myAccount.deposit(100));    // Deposit 1
console.log(myAccount.deposit(150));    // Deposit 2
console.log(myAccount.withdraw(50));    // Withdrawal 1
console.log(myAccount.withdraw(30));    // Withdrawal 2
console.log(myAccount.deposit(10));     // Deposit 3
console.log(myAccount.deposit(21));     // Deposit 4 - balance now > 100

console.log(myAccount.checkBalance());
console.log(myAccount.listAllDeposits());
console.log(myAccount.listAllWithdrawals());

  • Push a new object to the transactions array with a type of withdraw and the amount withdrawn.

Slight deviation from this user story, fix that and it should pass

Thank you that worked.
