        let randomIndex = Math.floor(Math.random() * uppercaseLetters.length);

Explanation:

• The function generatePassword takes a parameter length which is the desired length of the password.
• The string uppercaseLetters contains all uppercase letters of the English alphabet.
• The variable password is initially an empty string to which random uppercase letters will be added.
• The for loop runs length number of times, generating a random index value between 0 and the length of uppercaseLetters. This random index is used to select a random uppercase letter from the string which is added to password.
• Once the loop finishes, password contains the generated password of the desired length with only uppercase letters.
• The generated password is returned by the function.
