What a journey! ๐ŸŽ‰ I've just finished the Deep JavaScript Foundations, v3 course by Kyle Simpson on Frontend Masters.

This course took me on a deep dive into JavaScript, covering things like Types, Scope, and Objects. ๐Ÿš€ I learned a lot about how JavaScript works, and how to use Coercion, and got to explore the world of Scope and Closure. I also got to understand JavaScript's this keyword and prototypes better. ๐Ÿง 

I won't lie, it was a big course with lots of tough parts. But I stuck with it, and I'm so glad I did. Now, JavaScript makes a lot more sense to me, and I feel ready to take on any JavaScript challenge. ๐Ÿ’ช

Big thanks to Kyle Simpson for creating such a great course. If you're tired of guessing how JavaScript works or getting confused by specific outputs, this is the course for you! It's a game-changer for really understanding JavaScript.
