The API of this library is more complete because it is executed at runtime it can offer more things (observables, events, ...) which Angular doesn't have (but doesn't really need given that you can not change the translations) 👍456😄1🎉44😕1 ️67🚀16👀2 chaouiy on Apr...
ReactJS uses observable’s to find the modified components. Whenever setState() method is called on any component, ReactJS makes that component dirty and re-renders it. ReactJS使用observable(可观察量?)来找到有修改的组件,当setState()在某个组件中被调用时,ReactJS会make that component dirty 并且...
Vinayak I have worked on both Angular and React enterprise level applications , I find Angular appealing in terms of completeness , it has got everything observables to handle async state , dependency injection, reactive forms and what not , but in React I particularly like the simplicity , co...
As for "elements of set", here is my take on it: The propertime derivative would probably exist as some scalar field that is derived from the norm of a vector field based on relativistic length contractions of observables inside Euclidean space itself. Such does not lead to any "space-pro...

Observables+DOM elements is a leaky abstraction, and as a user I shouldn't need an intimate knowledge of how the UI is kept in sync with my data. This architecture opens up lots of various ways to optimize the rendering, but it's all completely transparent to the user....
Astronomers have estimated that there are around 200 billion galaxies in the observable universe. But when we see other types of galaxies portrayed in science-fiction films, they tend to have the same basic shape as ours. This would be an example of our human-centered biases. Although many of...
In order to get the CommandParameter you will have to pass it through with the command. Something like this.复制 this.ItemCommand = new Command ((parameter) => { this.ItemAction(parameter); } ); private void ItemAction(object parameter) { var item = parameter as Trip; this._...
only measure +1 or -1 (quantum exchange of momentum per NPRF), we can only get conservation of angular momentum in any particular trial when their SG magnets/polarizers are co-aligned. And, we cannot use classical probability theory to account for the conservation of angular momentum on ...
