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.
