This course clearly explains the code I've been, somewhat blindly, writing my whole career. I wish I had stumbled upon it way earlier.

Clear explanation of how frameworks like React work under the hood, and an awesome grasp of foundational concepts like One-way data binding, Declarative UI, Functional Components, and Virtual DOM.

Juan Taborda

I wish I had Will when I first started learning JavaScript. His energy is great throughout the whole course and genuinely wants you to learn. Thank you Will!

This is one of the best courses I've taken... ever. Will was so thorough and precise. This definitely gave me a much deeper understanding of JavaScript. It was such a motivational, life-changing experience for me. I know everyone is at a different place on their learning journey, but this was exactly what I needed to learn.

Bryan Tomlin

This has to be the best Node course I've ever done. Very detailed and explains the intricacies of how Node works behind the hood.

Israel Okwuje

It's amazing how much I've been able to learn about JavaScript thanks to different “Hard Parts” courses. Even the most complex concepts become clear. Thank you, and congratulations on your outstanding teaching.

Mathieu Haage

What I appreciated most is the teaching style. Complex topics are explained in a way that is both deep and approachable. Instead of memorizing concepts, I felt like I was building a mental model of how JavaScript executes code.

Svetlana Kostromina

This course is amazing and a must watch for any experienced JavaScript developer. Will breaks down complex and confusing concepts in such a way that its easy to understand. My only regret is not watching this course earlier in my career. Fantastic! A+++

Wow, I never heard of Will Sentance before taking this course, but he is an exceptional teacher. At first I thought it was a bit excessive how he used repeated blackboard examples to drill home a topic, but I've made flashcards based on the content in this course, and sometimes when I'm reviewing cards I can literally see his blackboard diagrams in my mind. Bravo!

Dylan Miller

This course provided me with a clear mental model of how JavaScript works under the hood. It also helped me big time in a recent interview where I was asked to explain the event loop, and I was able to confidently explain how it works in detail.

Adam Lapczynski

Wonderful course! One of the best courses I've taken! Will is an incredible teacher and you can tell by watching the couse that he loves what he does! This course is definitely essential for all JavaScript students.
