I need help with my credit card checker. I can’t get to spit out the valid1 array after doing modulo for x = i % 2;
here is some of my code.
Please help
const validateCred = (num) => {
for (i = 0; i < valid1.length; i++){
x = valid1;
x = i % 2;
if (x !== 0){
return x;
}
}
}
console.log(validateCred());

Hey @micro3769222521,

We are here to help :wink: .

But I do have a question first, how far are you with the Javascript courses? Looking at your code I can see you have some knowledge but other aspects make me ask the above question.

I am currently 49% finished. I do know there are some concepts that I need help on. My main concern is learning how to do word problems in codecademy. Thanks for the help.

Nevermind. I think I figured it out (and corrected the code as well).

I was looking at your code again and I don’t understand this line

for(let i = array.length - 1; i >= 0; i -= 2) {
checkDigits.push(array[i]);
}

can you help me?

hello, I seem to be hitting a wall too. 1) I’m vague where to start. I keep on printing out valid1.pop and valid1. reverse but that is it then I have a loop

validateCred = (isValid) => {
for (let i = 0; i <= valid1.length -1; i++) {
//then nothing.
}
I have gone back over javaScript loops again.

Thanks
