Great article but a terrible topic for a "beginner-level" tutorial.
A small introduction to PCI compliance requirements would be great to stop beginners from thinking they can process credit card numbers as easy as this...
The intended takeaways here are checksums and the functional-style implemention - definitely not intended as an introduction to financial processing.
Sure, that's why I think it is a bad topic for a tutorial.
The programming style is cool, but it would be better if you implemented another algorithm, something that could be used in a real world app, or at least warn the readers they should never get credit card numbers in their app (unless they are building a bank..)
Fair point!
I always thought credit card numbers were mostly just sorcery.
Thanks for demystifying it!
I'm using: creditcard.run/checker/
Hello Buddy,
I have found some related code that helps to validate Luhn checksum and it is easy to understand written in Javascript.
I attach code (Image Format) with this comment.
I would like to prefer one of the site that Generate and Validate Credit Card using Luhn Algorithm.
Hello Ben,
We've developed a credit card validator tool at VCCGenerator. But we need to validate the card details through javascript. Can you help with that?
The main advantage of the credit card generator is that it allows users to make use of the system even without the knowledge of the person using it. This way, a user will not be able to figure out whether the visa card generator is actually valid or not. Hence, people may end up spending more money on these fake generators than they actually have.
Hey Ben Lovy
Thanks for sharing information Validate a Credit Card or Debit Card Number with Functional JavaScript there are some sites on the internet which work with the Functional JavaScript one of the best examples is cardgenerators.org
Protip:
You can reference the end of an array by using negative integers.
i.e.
Instead of
.slice(0, len - 1)you can do.slice(0, -1)Ooh, thanks! Much nicer. JS is definitely not in my muscle memory yet.
Very nice article. kudos!
Great article - fascinating on a good few levels.
Thanks for sharing!
Hi Ben How can i create a script code like Credit Card Generator With Address
