I wish the author had written a Fundamentals of JavaScript Programming as well.

I read bits and pieces from a lot of different JS books, and studied the first half of Eloquent JavaScript. I spent most of my time reading stuff online (especially the MDN docs).

Consider using a site like CodeWars where you're tasked with solving actual challenges.

For years, I've read books and blogs as well as watched videos and learned some things, but, working through challenges is more motivating and forces me to produce. I rely on the same resources (books, blogs, videos), but through the lens of, "how can I accomplish X ?"

Not sure you will have a similar experience, but it works for me.

Definitely. I find that making solid progress on sites like codewars has been one of the best ways to improve my coding. Makes me better at planning as well as coming up with better solutions and is inherently motivating because you can hit well-defined goals in rapid succession.
