Excellent course

Aristeidis Bampakos | GDE for Angular | Author of the book "Angular Projects"

I am already halfway through @DecodedFrontend Advanced #Angular Forms course and I am amazed by the detail of the content provided 🤯 Dmytro has done a great job demystifying concepts of Angular Forms that are hard to understand 💯 - See Tweet

This Is The Best Of The Best Regarding Resources For Learning Angular Forms

Fatima Amzil - Google Developer Expert for Angular, Software Engineer, and Writer

This is the best of the best regarding resources for learning Angular Forms! Thanks a lot, @DecodedFrontend, for making such high-quality content about Angular Forms. I wish I had this course years ago when I started learning Angular!

Best Course about Angular Forms

Amadou Sall – Google Developer Expert for Angular & Frontend Software Engineer at Air France

This is the best and the most comprehensive course about Angular forms you will find on the Internet. It covers everything from the basics to the most advanced topics. Dmytro is such a great teacher. Even if you consider yourself an Expert in Angular, if you don’t take this course, you’re missing out on something big.

An Excellent Resource for Advanced Angular Forms

Aurora Shehu | Senior Angular Developer

I recently took the Advanced Angular Forms video course and was thoroughly impressed. The course was well-organized and easy to follow, with clear explanations and plenty of examples to illustrate key concepts. One of the strengths of the course was the instructor's ability to break down complex concepts into manageable chunks.

Incredible Content

Andrey Chayko | Senior Frontend Developer at Semine AI

If you’ve ever wondered about how Angular forms really work, then this course is what you are really looking for! A massive thank you to Dmytro for such incredible content and “under the hood” sections.

New level of Courses

Viktor Kushnirenko | FE Developer (Angular)

My best investment for last year. What a surprise was for me when besides the main theme (advanced angular forms) I gained also some best practices during training. Simple about complex, excellent explanations and super convenient prepared GIT project. See the full feedback on LinkedIn

Invaluable Material

Uğur Salın | Frontend Developer

It is hard to find quality content on advanced Angular concepts. It is even harder to find them explained in a simple and concise manner. Luckily, Dmytro excels in both. Great job making custom controls very easy to understand.

This course is something incredible!

Kostiantyn Kifor | Frontend Developer

In my opinion, Dmitry currently creates the best Angular content. He explains everything very clearly. After this course, you will master all the skills and knowledge about forms perfectly! As for the price-quality ratio, this is an extremely cheap price for such content!

Absolutely Fantastic Course

James Evans

This is an incredible course, it is the most in-depth angular forms course I have ever seen and I have seen quite a few. Dmytro goes into so much detail on each of the features of how angular forms works and drills down into the angular source code to give a very solid foundation which you can carry forward into your development. It’s definitely not a beginner course! Many thanks to Dmytro for putting together such a detailed course on a very complicated topic.

This Is The Great Content

Luis Castro Cabrera | Frontend Developer

Just bought the Angular Forms course by @DecodedFrontend and I already spent a couple of my insomnia hours looking at it… this is great content and top-quality explanation, thanks for this Dmytro
