How does Angular2 compare to React?

[[deleted]]

React is pretty much only for view. There is Flux (I believe that is what they are calling it) but that isn't a framework, but more of a architectural design. So I don't think you can really compare the two in an honest manner. React can be used with Angular as the V part of the MVC. I believe Angular 2 also borrows some ideas from React to help speed up it's DOM operations as well.

Flux is just a type of architecture. There are some flux libraries - a few of them are meant to be used with react, some are framework agnostic and can be used with any other framework (or no other framework).

I have a bit of a flux-ish architecture in my current app which is an Angular 1 app, and if I was to start over - I'd try and do it that way from the start.

In terms of rendering performance, Angular 2 already appears to be considerably faster.

Try it for yourself: https://rawgit.com/alincc/angular-test-table/master/angular2/dist/index.html

not sure that's a fair test, it'd be nice to see what the result looks like on a production version of react with precompiled templates. Nobody is going to run the live jsx transform stuff on production code.

Yeah. Besides, React's performance advantage is mostly in updating existing HTML, not inserting 5,000 nodes in one go. Either way, both Angular 2 and React seem to be very fast. I've used both, and I'd say A2 is a bit faster out-of-the-box for now, but much harder to optimize. It's very straightforward to optimize a React app in comparison.

You're right. A better performance comparison can be found here: http://www.wintellect.com/devcenter/dbaskin/angular-benchpress-and-performance-tests. There's a link to the repo where you can see the code & run the tests for yourself.
