Nop, sticking with Atom :) it's awesome because it lets us write plugins with web technologies. Even though they pull React off of the core, it's still possible to use React to write plugins :)

Modifying the DOM is usually the bottleneck in web apps. To get a fast app (extreme simplification), you need to only apply the minimum set of mutations. It turns out that in a large codebase this is extremely hard to do. React asks the dev

The problem with Transferable Objects is that they only work for raw buffers. This is great for math intensive tasks such as image processing, but not that great for UI related tasks. We want to be able to share js objects, arrays and strin

For accessibility you can look into what pdf.js does. They put a transparent text on-top of the pdf text (canvas). So you can select it. Pretty clever :)

You can define a setter that throws in order to throw without using 'use strict;'. However, additions will still be silent :( https://gist.github.com/vjeux/6b390e6a6bb51e24b646 __DEV__ = true; var a

React immutability helpers pros: - Work on regular JavaScript Object and Array so it's easy to get started and integrate to your app - You don't need to wrap objects inside of Immutable to use it and you can use `obj.key` and `arr

If you think you can make it better in React, pull requests are more than welcome. For example, we didn't have batching when we open sourced React and it was written by the community :)

The reason why Mori scales better is because it implements arrays via a tree of 32-slot arrays. So unfortunately, you cannot use normal JavaScript data structures and have to re-implement all the array methods that know how to deal with thi

(a) You can use the key attribute in order to get DOM reuse. If you are looping over N keys then React is going to reuse the nodes and move them around. (b) You can implement shouldComponentUpdate in order to have a quick way not to re-rend

Before we launched React we had a big discussion as whether we should change the name or not. React is completely different from everything that's called "reactive programming" and we were afraid to cause confusion.
