This was the most transformative JavaScript course I’ve ever taken. Will’s teaching style made even the hardest concepts like closures, prototypes, and async feel deeply logical and clear. I finally understand how JS works under the hood. Thank you for this eye-opening journey!

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! 🚀
