Javascript Code Error

Answer 1

Other than the syntactical problems Wyatt pointed out there was another issue. You do not need for-loop to iterate over the entries in the bankAccountsList object. Objects in Javascript have name-value pairs, where the name is used as the key to access the value and it needs to be unique.

Therefore you can simply look an account up by doing the following: backAccountsList[accountNumber]. This is much a faster (O(1) time complexity) than iterating through all the possible entries in the object.

In addition to the change above I also cleaned up the code by removing all the unused variables and fixed the missing braces in the code.

let bankAccountsList = {

126347869: 200,

234539790: 400,

348079070: 900

};

function withdrawMoney(amount, accountNumber) {

// check length of the accountNumber

if (accountNumber.length == 9) {

let currentAmount = bankAccountsList[Number(accountNumber)];

if (currentAmount != undefined) {

let message = "<br/>" + "Account: " + accountNumber + "<br/>";

message += "Money in the account: $" + currentAmount + "<br/>";

if (amount <= 2000 && amount > 0) {

currentAmount = currentAmount - amount;

message += "Amount withdrawn: $" + amount + "<br/>";

message += "Updated account balance $" + currentAmount;

return message;

}

return "Enter the amount between 0 and 2000";

}

}

return "<br/>" + accountNumber + " bank account does not exist" + "<br/>";

}

console.log(withdrawMoney(100, "348079070"));

console.log(withdrawMoney(-10, "126347869"));

console.log(withdrawMoney(2001, "234539790"));

console.log(withdrawMoney(1, "234539790"));

console.log(withdrawMoney(100, "126347869"));

console.log(withdrawMoney(500, "234539790"));

console.log(withdrawMoney(50, "34567790"));

Answer 2

The syntax errors can be found by using an IDE or text editor with a Javascript Linter like ESLint. I would recommend downloading either Atom (free) or Intellij.

You are missing a { at the end of the line:

function withdrawMoney(amount, accountNumber)

You are calling withdrawMoney with a string as the accountNumber instead of a number.

For logical errors:

1. You are only checking if the account number is less than or equal to 9, when you need to check if it is exactly 9
2. You are not setting accountFound
3. counter is unused
