To get paint flashing after rendering elements on Chrome,
1) CTRL + SHIFT + I
2)ESC KEY
3)OPTIONS button (3 dots symbol) at lower left corner
4) rendering

A teacher can make the student hate the subject or can make them fall in love with it. I am loving React! You are a great teacher

Finally understood the difference between normal and React DOM rendering. Good example.

Das Video unterscheidet sich von den ähnlichen durch die gut strukturierte Erlärungslogik, die leicht zu verfolgen ist. Man kann sich nur vorstellen, wieviel Zeit und Kraft investiert wurde, um so einen hervorragenden Kurs zu schaffen. Herzlichen Dank dafür! Bitte nur so weitermachen! Liebe Grüße aus der Ukraine.

Very understandably explained tutorials. Keep up the good work.

[AlphyGacheru]

Wow, finally I understand the concept

[sekhar]

Max, you are Godsend!! Amazing tutorials. I found your channel while I was searching for angular 2 tutorials. Watched the video series and got a simple SPA that deals with CRUD based REST services written in Java (already existing) in 3 days!! Decided to give React a shot to see which one I'd prefer. This time I knew where to go. Your channel of course. Amazing work mate!! Can't thank you enough!!

Just realized about flash painting existence, really cool by the way. And what an amazing work you have done with this ReactJs video series, keep up the good work.

That paint-flashing is super useful for tracking how components render and rerenders. I think you should include this entire content into your course. So bad your React Course does not explain this.

[Me_and_nature]

Your doing great..thank you so much for the video

[foodfairyshi]

Wow, I am glad that I found your video! very helpful. Thank you

[alokranjan]

I have one doubt here regarding virtual dom rendering. I tried using paint flashing using JS and AngularJS, but in both case it was painting only the changed item not the whole DOM. So how react Virtual DOM is different from others?
