What They're Saying

I just completed "JavaScript: The Hard Parts, v2" by Will Sentance on Frontend Masters! Will is such a insightful and funny guy, making this whole learning experience quite entertaining. Can recommend. 100%.

This is the best JavaScript course I have ever watched!

Vosiqxoja Maxmudov

I would confidently say that I am a seasoned Python/Django dev, but I've been wanting to learn more about JS/TS. Decided to start my journey with this course to understand async/await/promises, but to my great surprise, I've also learned an _incredible_ amount about what is actually going on behind the scenes of programming languages in general. I've already moved my schedule to watch Will's other courses. Absolute legend.

Zac Ruiz

Will is the best. Everything he says just sticks!

George Kalyvianakis

Will Sentance doesn't just teach JavaScript - he rewires how your brain understands it. Closures, async, OOP - finally explained in a way that actually clicks. This is the course I wish had existed when I started.

Bilal Haidar

An outstanding course with excellent explanations for achieving a deep understanding of JavaScript! I've never experienced such a thorough deep dive in any other course.
