Unlocking the Secret Code

Presenting the question:

checkPassword([["Peter", "P"], ["Sarah", "S"], ["Ethan", "R"]], {"Peter": "P", "Sarah": "Q", //"Ethan":"E"})

Answer №1

Are you attempting to manipulate an object like an array and compare array to object as values?

To achieve this, you should treat the object as an object and compare the values within. I recommend using the following code for this task;

function findMismatchedPasswords(attempts, credentials) {
  // Initialize an empty array
  let mismatchedPasswords = [];
  // Iterate through the object, extracting key-value pairs
  for (const [key, value] of Object.entries(credentials)) {
    // Iterate through the attempts array
    for (var i = 0; i < attempts.length; i++) {
      // Extract name and password from the attempt(s)
      let name = attempts[i][0];
      let password = attempts[i][1];
      // If the name matches the object key and the password does not match the value...
      if (name === key && password !== value) {
        // Add this attempt to the mismatched passwords array
        mismatchedPasswords.push(attempts[i]);
      }
    }
  }

  return mismatchedPasswords;
}

// Test the function!
console.log(findMismatchedPasswords([
  ["John", "J"],
  ["Mike", "Y"],
  ["Ion", "F"]
], {
  "John": "J",
  "Mike": "C",
  "Ion": "I"
}));

This code accomplishes your request, but there are more efficient ways to handle this scenario. For instance, entries that do not exist at all (e.g.

["Dave": "davina"]
) will not appear in the list of mismatched passwords.

I have provided a basic solution here; feel free to enhance it further!
