good learning but the pace of instructor is fast

By Adrian Buturuga on 5/12/2026

It's a strong base for typescript explained properly. It gets complex at the end so you are probably not missing anything. Also got few questions in the interviews so it can prepare you for one for sure.

Excellent explanation

By Rachel Hall on 2/19/2025

I'm a fan. I'm liking this course a lot more than another udemy ts course i tried.

By Denis Pipchenko on 1/11/2025

First I thought it misses a few advanced details. But then I realised - it helped me to cover 90% of preparation to the TS part of interview within only ~3 hours of video! Many other courses have 15+ hours, which turn into a calendar week easily (at least) with proper attention, coding and reiteration on everything - that's a huge difference. So I believe this is an amazing course that does its job very well and saves a ton of your time!
