1. How React's reconciliation Algorithm Works? 2. How does React handles aysnchronous updates? 3. How does React solves optimization problem and is it good to always optimize?

[@bastienv6233]

You the boss man ! I was searching everywhere to get a quick example of react optim and I found it as usual in one of your video!!

[@colab_ora]

Pedro check the response on 9:38, just if you want to blur it or something, so youtube doesn't flag you. Great video, thank you for sharing!

[@PedroTechnologies]

Good point! Thank you!

bro I love your videos , always trying to make people understand the fundamentals , exactly how I want to learn . currently I think I'm intermediate in react and it's really hard to find videos that talk about advanced stuff , most of them just for the basics that's all . I would love to see more advanced stuff like this in the upcoming videos .

I think, for advanced answer, you should mention, that there is no such thing as vdom. It is just an abstraction. Basically, react based on a tree of ‘dumb’ react components and a tree of states of these components, or fiber nodes. And depending on the changes in the fiber nodes, re-renders occures.

[@alisonoz7219]

Amazing video! I'd like you to share a NextJS tutorial video!

[@suspiciousactivity4266]

Great vid. Very helpful and informative as always.

[@shakilahmed6870]

what did you blur at 9:36?

[@PedroTechnologies]

There was data from this example project which included stuff written by my viewers cause the project is public. There were some hate comments so i wanted to blur them

[@williamrinaldi1808]

Prop changes do not trigger rerenders. If props are stored in state, the state change in the parent causes rerender.

[@PedroTechnologies]

Prop changes do trigger re-renders if they are being used

Thanks bro.

[@tylermyers8735]

Thanks for the video man, quick question: You mentioned that React keeps TWO copies of the DOM? I'm not sure I've ever heard this before. Does that mean there are technically three DOM's? The actual DOM, and then TWO copies of that DOM in memory that React uses to reconcile the state + props changes?

[@tylermyers8735]

Can anyone clarify this for me? This has been driving me insane.

[@nocategories3398]

@@tylermyers8735 Yeah, I was under the impression that the virtual DOM is compared to the Real DOM and then changes accordingly.
