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
If a stateful react component C is at position P in VDOM V at time T
then
where will C be in VDOM V' at time T+1 after a re-render ?
For example in this fiddle the state of the first stateful component is "transferred" to the second stateful…
I'm trying to change values of react controlled inputs when I type in the browser.
I have provided a code example.
The third input is automatically filled in if the first two inputs have a value. But if they are empty how can I allow the user to…
I have a "simple" question about Angular 2 internal DOM manipulation. Is Angular 2 using Virtual DOM, Incremental DOM or what. I have been looking all over the internet to understand what Angular 2 uses for DOM manipulation internally but I can't…
I am building a large application using React where a shared parent component handles all the state for multiple children. Some of these children render lists of over 1000 items.
I realize that toggling a boolean inside the parent with setState…
Currently trying to build some React components using D3 math. However, when it comes to transition/animation, kind of facing a wall. It's not straightforward.
I saw folks are using libraries like GreenSock. How this affecting on Virtual DOM? Does…
I want to get an HTML string representation of my Maquette view in order to prerender it to a static html file. React has ReactDOMServer.renderToString. Is there a similar method for Maquette VNodes?
In the virtual DOM, onChange is triggered every time the content of the input is changed. In the regular DOM, onChange is only triggered when the input element is blurred.

With the React virtual Dom, I understand the subtree part, or at least I think I do: React will only re-render from components that had their setState called, and potentially all children of these components. i.e. components that haven't had their…
New to react and I'm wondering if there is any work around to get past this error:
_registerComponent(...): Target container is not a DOM element.
EDIT What I'm trying to do is:
I have a react function…
I'm trying to understand component re-rendering in react vs. angular. My understanding is as follows:
React uses Virtual DOM. This is an object in memory that models the DOM. Each time some state changes, the new object is compared to a snapshot of…
I have a React app embedded in an external .Net app. all works fine, but I have a plugin on the main app to translate the content of entire content including the content inside the React App which is a problem because the real Dom can't conciliate…
I have read many blogs on render and commit phase in react. But couldn't understand much exactly. They mention render phase is a slow process and commit phase doesn't takes time.
In simpler words, is rendering checking the current Virtual DOM with…
Can somebody please take away my confusion about react rendering process?
when we update the state and the browser re-paint the UI of the updated component. is that what we call rendering? or when the virtual dom informs the real DOM (browser dom)…
