Oh, this is a huge milestone! Finally diving into modern JavaScript with ES6+. It's exciting to think about making code cleaner and more enjoyable to write after the fundamentals.

So ES6+ is all about the ECMAScript specification, which makes sense. It's good that they're immediately addressing browser compatibility too, because knowing the syntax is only half the battle.

Wow, over 20 new features since 2015, that's quite an evolution! It's interesting how they're marking the versions by year now with ES2015, ES2016, and so on, rather than just roman numerals.
