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...
"test" is an array of object in my vue data  var vue = new Vue({   el: '#content',    data: {     test: [       {         array: [0, 0, 0, 0]       },       {         array: [0, 0, 0, 0]       }     ],     number: 0   },    methods: {...
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?   <!DOCT...
I have nested click event handlers within a component:  class ListItem extends React.Component {     ...     render() {         return (             <div onClick={this.save}>               ...Content...               <span onClick={this.onDe...
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...
when i use react ,i find these two life cycle are too similar, componentWillReceiveProps receive nextProps as argument, shouldComponentUpdate receive nextProps and nextState as arguments, so i think shouldComponentUpdate can do the same thing and mor...
Here's my naive understanding of how the DOM and browser works  Whenever something in the DOM ( the real dom ) changes the browser repaints or reflows that the DOM. So in simpler terms every time the DOM changes browser needs to recalculate the C...
I read that ReactJS is very fast compared to other frameworks because if uses virtual dom.   What I am not able to understand is ultimately all framework has to push dom objects in browser. How virtualDom helps gaining speed?   Lets say if I want to...
For example, a component has the initial state of {loading: true, setup: true} and when changing states like this:    this.setState({   loading: false,   setup: false })     Are there any chances at one point that loading is false and setup is still...
How do I properly define radio buttons using Maquette so the text will render? If I use a <p> element the text appears, but on a new line.    var h = maquette.h; var dom = maquette.dom;  document.addEventListener('DOMContentLoaded', fun...
