I think the docs are very good and more than enough not only just to get started, but also to keep you going.

I did a search for coupon codes and I found the exact coupon code from [1].
Can I ask, what would the problem be if the code was affiliated with an affiliate promotion?
The end user pays $10, which I think we can both agree on. It's a "NET" benefit for HN users to learn something new very cheaply.
If couponkoo negotiated with the vendor of the product, so that they can advertise a coupon and get some kick back, you know because they too have to keep the lights on.
Is that such a big deal now on HN? Can you please explain yourself because I don't see an issue here personally!

Shame I cannot down vote you yet!
Specifically, I used learning Vue as an opportunity to upgrade a simple jQuery-based SPA (with a PHP backend) to ES6, JS modules and Vue. It was a little hairy to bite off all of that stuff at once, but the Vue community was really helpful. In contrast to more monolithic frameworks I didn't have to port everything at once, and the re-implementation of the bits I did port are sooo much cleaner.
FWIW, there's a highly-rated Vue.js 2/Vuex Udemy course on sale for an impulse price of $14 (normally $190) as I type this. With the caveat that I just bought the course myself, at that price it seems like a useful resource even if you only have a cursory interest in Vue.
