This looks super dope. I also love Observable and have wanted to find more ways to leverage it. This seems perfect!

This was a great reference when I started learning JavaScript. It just didn't go over the language, but also gave a great history of programming in general and why JavaScript is structured how it is. A lot has changed in JS land since the first version came out so I look forward to have the author tackles it/

Agreed. This book's conversational style and carefully-worded explanations of core concepts from multiple paradigms helped me begin to grok javascript beyond just $('.that-thing-there').doStuff();

I look forward to all the R2D2 mods this will birth.

Agreed, it does look like R2D2.

It was as if Apple lured R2D2 to the dark side and released as the Mac Pro!

I absolutely love Firebase. It's dead simple to setup and a pleasure to use.

Have you tried Meteor? I've been comparing the two.

I haven't played around too much with Meteor actually. Both seem like great technologies though. I've been using Firebase to store data whereas I know with Meteor you can still roll Mongo or any other DB.

Didn't realize you could do loops in SCSS. Awesome.

This could interesting from development, but LiveReload exist, so I'm curious what the market is. As others have said, if you could scroll to the top without firing the reload immediately (and it worked on mobile) this could be a neat tool.
