ReactJS Basics - #9 How does ReactJS update the DOM?

Thank you

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

Why r u using a light theme

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.

All good, but comparing Actual DOM and Virtual isn't correct. Operations of Virtual DOM go on TOP of DOM operations. So they work together and using Virtual DOM main goal isn't to make Actual DOM faster but one of the ways for declarative development. Tho there are other ways of not using Virtual DOM like in Angular or Svelte frameworks.

Paint flashing doesn't work proerply it shows same results for both react and normal application

Then what happens in plain javascript. Let's say we are not using react and writing in plain javascript and we make a dom change, then what happens in that case, does it rerenders the whole dom or only change the node which is changed like react?

Is Virtual DOM part of Client Side Rendering? OR Virtual is different from Client Side Rendering?

Is there an anual subscription for all Academind courses?

your channel logo and thumbnails looks similar to fireship. I often get confused

Is there any rules, like only displayed state variables get updated? What about those props passed into children, those automatically cascade or you have to store them to state? I have a pretty complex app and there's 2 cases where it doesn't update ever. I'm trying to figure out why and maybe 1 reason is those state variables are only used in if statements. The other one has a passed-property that's put into a hidden field, maybe those don't cause a dom update. Just my first guesses but I wish I could find some kind of rules checklist. Some times I'm saving props to state just because I don't know if I need to or not

Thank you!

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

Nailed it✌

nice

Nicley explained...

Love💖

Thank you sir

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.

quick and to the point

Great explanation!

Nice explanation 👍

I was really struggling till now, You explain the things in a very simple manner. 💛💛

Thank you for this video!

Wow, finally I understand the concept

great tutorials, everything nicely explained, but please Max make sure you pronounce things properly, it drives me mad when I hear 'Wirtual Dom' not 'Virtual Dom' and I can't focus on the great content...

Can I use setInterval without using useEffect? I tried but seems like it create infinity loop. I want to start counting from 10 to 0 when button clicked

Thank you so much for video.

Nice explanation, does angular works the same way with the DOM?

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

very important to understand why reactjs is so fast. Thanks for the video max.

Holy cow that "Paint Flashing" feature is sooooo useful. Wish I would have known about that before. Thank you, thank you, thank you

Awesome explanation.

Nice explanation.

you are awesome MAX :)

Hi Max
Which IDE did you used in this reactjs tutorials?

Thank you for all the courses. You're doing a great service towards the dev community.

any way you could do this with a form? say i had a form and wanted to change the state of a <p> with the input from the user. any suggestions?

Thanq very much bro.. u made my future with React

amazing ,amazing ,amazing

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?

rendering setting is that extension or what? But was really cool stuff! can we know what exactly it is?

Nice videos, Its helpful for learning react js. Thank you, Max !

0 dislikes. Completely understandable why. Thanks

Very, very good explanation!

you are the best can we add , jQuery inside the react component ?

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.

Wonderful tutorial on React! Keep up the good work sir.

Awesome, nice explain. Continue with this. ;)

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
