Credit_Card_Checker code help

I attempted to complete this project using the Codecademy workspace, but I was getting an error message. Can someone please explain what I’m doing incorrectly?

Thank you!

Glenda,

The link you provided was broken, but I think this is your profile?

Not sure what errors you are receiving, but I found a number of typos when looking at your code. The cleaned up version would look something like this:

// All valid credit card numbers const valid1 = [4, 5, 3, 9, 6, 7, 7, 9, 0, 8, 0, 1, 6, 8, 0, 8]; const valid2 = [5, 5, 3, 5, 7, 6, 6, 7, 6, 8, 7, 5, 1, 4, 3, 9]; const valid3 = [3, 7, 1, 6, 1, 2, 0, 1, 9, 9, 8, 5, 2, 3, 6]; const valid4 = [6, 0, 1, 1, 1, 4, 4, 3, 4, 0, 6, 8, 2, 9, 0, 5]; const valid5 = [4, 5, 3, 9, 4, 0, 4, 9, 6, 7, 8, 6, 9, 6, 6, 6]; // All invalid credit card numbers const invalid1 = [4, 5, 3, 2, 7, 7, 8, 7, 7, 1, 0, 9, 1, 7, 9, 5]; const invalid2 = [5, 7, 9, 5, 5, 9, 3, 3, 9, 2, 1, 3, 4, 6, 4, 3]; const invalid3 = [3, 7, 5, 7, 9, 6, 0, 8, 4, 4, 5, 9, 9, 1, 4]; const invalid4 = [6, 0, 1, 1, 1, 2, 7, 9, 6, 1, 7, 7, 7, 9, 3, 5]; const invalid5 = [5, 3, 8, 2, 0, 1, 9, 7, 7, 2, 8, 8, 3, 8, 5, 4]; // Can be either valid or invalid const mystery1 = [3, 4, 4, 8, 0, 1, 9, 6, 8, 3, 0, 5, 4, 1, 4]; const mystery2 = [5, 4, 6, 6, 1, 0, 0, 8, 6, 1, 6, 2, 0, 2, 3, 9]; const mystery3 = [6, 0, 1, 1, 3, 7, 7, 0, 2, 0, 9, 6, 2, 6, 5, 6, 2, 0, 3]; const mystery4 = [4, 9, 2, 9, 8, 7, 7, 1, 6, 9, 2, 1, 7, 0, 9, 3]; const mystery5 = [4, 9, 1, 3, 5, 4, 0, 4, 6, 3, 0, 7, 2, 5, 2, 3]; // An array of all the arrays above const batch = [ valid1, valid2, valid3, valid4, valid5, invalid1, invalid2, invalid3, invalid4, invalid5, mystery1, mystery2, mystery3, mystery4, mystery5, ]; // Add your functions below: const validateCred = (arr) => { let reverseArr = arr.reverse(); let sum = 0; for (let i = 0; i < reverseArr.length; i += 2) { sum += reverseArr[i]; sum += reverseArr[i + 1] * 2; if (reverseArr[i + 1] * 2 > 9) { sum -= 9; } } if (sum % 10 === 0) { return true; } else { return false; } }; function findInvalidCards(arr000) { let invalidArr = []; for (let j = 0; j < arr000.length; j++) { if (validateCred(arr000[j]) === false) { invalidArr.push(arr000[j]); } } return invalidArr; } let arr = [4, 5, 5, 6, 7, 3, 7, 5, 8, 6, 8, 9, 9, 8, 5]; let arr1 = 6; console.log(validateCred(valid3)); console.log(findInvalidCards(batch));

Thank for your feedback! Unfortunately, I’m still getting an error message even though I followed your example code exactly. This happens a lot since I started the JavaScript section of JavaScript even when I use the ‘View Solution’ answers. It didn’t happen with the HTML and CSS sections. It’s frustrating!

Thank you again for your feedback - I appreciate your response!

What does the error message say? Can you download VS Code? That is a free tool that will be very helpful to your efforts.

I don’t get an error message with VSCode. I only get error messages when I’m trying to complete JavaScript projects in the Codecademy site.

I see, unfortunately unless you share the error message you are receiving in Codeacademy, it is difficult to know what the issue is.

Sorry - I moved on before I saw your message.
