Frequently asked questions

What prerequisites do I need to have before taking this course?

You should know how to use HTML, CSS, and JavaScript. Being familiar with general web development terms such as what is an API would make sense too.

If I purchase the package with the 1:1 video call included how will that work?

We will schedule the call whenever you are ready and will try to do my best to help you. You can use that time to ask me for help regarding solutions to your React exercises or general career advice. We can also split the 60 minutes into 2 calls of 30 min each. The calls will be done via Zoom or Google Hangouts at a time that is most convenient for you. Just email me if you have any questions and I am sure we can find a solution.

Is the learning material up-to-date?

Technical books are usually outdated soon after their release, but since this book is self-published, I can update it as needed. At this point, the code from the book is made for React 18 (the most recent release) and I will update it as soon as a new version comes up.

What if I don't like it? Can I get a refund?

I'm sorry to hear that you're not happy with the book! Yes, please send a refund request to daniel@js-craft.io within 14 days of purchase and I will fully refund you the price. Not mandatory but I would appreciate it if you could provide the reason for the refund so that I can improve the book

Can I read the book on my Kindle?

Absolutely! The book comes in PDF and ePub formats. Kindle supports both of them. You can use Amazon's "Send to Kindle" service to upload it to any of your Kindle devices.

Do you support Purchasing Power Parity or student discounts?

If you live in a country with low purchasing power, or you are a student mail me with your details and some proof (student ID, etc.) and I'll organize a special discount for you.

Can I share the book with my friends and coworkers?

The book license is for one person only. I would ask you to respect that and not distribute it to others. Please email me if you have any questions or concerns.

Can I purchase several copies for my team?

Yes. Send me an email and I'll organize a team discount and can also offer bulk course enrollment and account setup.
