Fantastic course, as always from the great Will Sentance! The course made some of the concepts in the field of AI less intimidating while building great mental models for understanding.

I just finished "The Hard Parts of JavaScript OOP" by Will Sentance on Frontend Masters! I loved how Will tackled JavaScript object issues and offered diverse solutions until reaching the OOP approach, which just prototypes behind the scenes. Highly insightful! 🚀

Will Sentance has the best way to describe closures in JavaScript, a rather advanced concept. Definitely recommend his course "JavaScript: The Hard Parts" on Frontend Masters.
