Use virtual-dom for questions related to an object model which mimics the structure of and intercepts events normally handled by the real document object model (DOM).
The virtual-dom applies of the technique of double buffering to the DOM. It is used for many purposes, including:
security: sandboxing DOM mutation
performance: minimization of repaints and reflows
testing: performing static analysis on the rendered tree
I saw a React dev talk at (Pete Hunt: React: Rethinking best practices -- JSConf EU 2013) and the speaker mentioned that dirty-checking of the model can be slow. But isn't calculating the diff between virtual DOMs actually even less performant…
From ReactJS wiki page about Virtual DOM:
React creates an in-memory data structure cache, computes the
resulting differences, and then updates the browser's displayed DOM
efficiently. This allows the programmer to write code as if the
entire…
I understand that React creates a virtual DOM and compares the difference and then just updated the actual element of the real DOM but how is that more efficient if I change it manually? Via getElementById or by using the jQuery function?
There are lots of SO questions and blogs on the internet attempting to explain what virtual dom is, but this question is about why this kind of optimisation has to be to implemented in JavaScript/as part of a framework, rather than by the browser…
I understood how change detection works in Angular 5.0.
Can some one help me to understand how the same works in React and how much it was different from Angular's ?
I have a React component which has 2000 elements and based on some filter conditions I update my state, which internally causes re-rendering. Everything seems to be working fine. But when I togglefilter from 2000 elements to say 1000 elements and…
Let's say we have a parent component and multiple functional child components. I want to clearly know if the parent re-renders does the child re-renders or not.
After going through a few articles I came to know there are 3 ways we can detect…

It is not advised to use Bootstrap directly with React because Bootstrap's JavaScript may alter the DOM directly, interfering with React's Virtual DOM system. Can one say the same about Angular (2+)?
I know that this subject has been discussed a lot obviously, but I'm not sure how to research my question that is rather specific and I hope it follows the rules here.
I know that to decide whether to update the DOM or not, react compares the…
I have an Elm app. A while ago I realized that my app was crashing locally when I used FontAwesome icons. I came to understand that it happened because I chose SVG icons and therefore FontAwesome was modifying the DOM. That conflicted with Elm's…
