Will Sentance

This is the best course I've watched about Javascript. Will is a fantastic teacher and I enjoyed how he engaged with his students by asking questions to refine their technical communication.

This is one of the best course I've ever done! Will's passion for Javascript and teaching is really inspiring! I can't wait to dive deeper on the other hard parts courses.

Basically a map of how all frameworks and Vanilla JS work under the hood. Shows the complexities of UI development on the web, and why it is that way.

I've been professional coding in Javascript for over 5 years now and this course made a hell lot of topics way clearer for me. Wish I would've seen this at the beginning of my career and will definitely recommend this to every new dev in my team.

I’m a 5-year mid-level frontend dev. I’ve shipped apps, debugged race conditions, and argued about this in code reviews. I thought I knew JavaScript, but this advanced course proved me wrong. Hands-down the best learning experience of my career.

Very well-explained course. Will uses a tactic of repeating the concepts over and over with visual explanations, which makes it easier to understand and remember what was said. Also, very good exercises and questions that helped consolidate the lessons.
