I've had enrolled for angular course in udemy but had no idea max has a YouTube channel. I've made it a habit to watch at least one of your brilliant YouTube videos before I sleep. Thank you so much max for these videos.

You might have no idea how valuable your tutorials and thus you are to me.. Can't thank God & you enough. You helped me in a major way to understand Web development. Thanks Max!

[johnchase]

This video has helped me understand the differences in a big way. Thank you for putting a difficult subject in all its variance into one understandable lesson!

[bhumisaxena]

Thank you max, I was very confused for the last 5 to 10 days about callback, Promises, observable, and Async/Await. I couldn't find a Blog or video where I can understand the function processing or main difference between all these. Thank you so much for making this video.

Is there something that this guy can not explain easily and correctly? u have the gift of teaching Max ;)

[jakubrpawlowski]

I'm preparing for interview and I was just about to write this myself and then I decided to check if Max doesn't have it already and I was not disappointed! :)

Dear Max, if one day the planet earth becomes a harmonious civilization, set free from evil, it will be thanks to people like you. Whether you realize it or not, you are making the world a better place by the way you teach because it speaks to me and all your students not only on an educational level but also in a way that makes me love my work more than I could ever love it on my own. It is because of people like you who make learning fun and spreading high quality education to those who are less fortunate, they will one day become excellent programmers one day capable of providing for their families whose kids will become just as good as them. Thank you so much for all your work.

Oh my God! This is exactly what I am looking for! You are the best as always!

[santoshkadam]

Max you are great !. His voice level is always good enough that we never get bored. He teaches some of the complex concepts in simplest possible way.

[goddardpk]

Max, thanks for clarity and distinctions between Promises & Observables!

[AlexeyR]

I have to rethink some ideas and want to look deeper under the hood, so I return to Max's videos. I have to say "Thank you, Max" again. Great comparison of methods in JS. I am just interested in why RxJS is in front of async/await 🙂

[yunkipaik]

Thank you, Max. Yours is the best tutorial on Promise. Hands down!

[namahshrestha]

You are totally the best man!! Taking your udemy courses was the best thing i did..it landed me a job!! I totally killed it in the interview..Cant thank you enough.

Lehrer

Useful contents shared in just one video.
Max, thank you so much.

[samithakulatilaka]

Great tutorial on the differences of how we can handle asynchronous programming. Thanks Max.

[kodecraft]

If I could like this more than once I would. This video is a must-see.

[vaibhavtekade]

One of the the best tutorial, clean and simple. Awesome Maximillian...

[FangerZero]

This video is great!!! I've had a very hard time understanding observables, and showing the same exact code in different fashions has really helped me. Thank you!
