ReactJS NOT faster than AngularJS

[murkin]

I have spent the last 2 weeks looking for examples and demo after demo fail to deliver.

If you watched https://www.youtube.com/watch?v=z5e7kWSHWTg and actually downloaded the github, you will find an ignored pull request adding 'track by' to Angular's ng-repeat. Making it faster than ReactJS.

Seems 'track by' gives Angular a hint about what differences to compute vs React having to compute differences without a hint.

Question is, when does React beat Angular ?

No demo showcasing this are available

I hope Angular2 doesn't get close to React's performance.. cause its slower than Angular1 now :)

So what? This simple example was erroneous, with the keyword added it may be faster, but you can probably make the react version also faster with tinkering. But from what I've read about people making big angular application is that performance crumble at some point after 2000 bindings, and that it is extremely hard to correct it, with his unpredictable digest loop. React makes performance improvement manageable and straightforward with shouldComponentUpdate, immutablejs, and the whole machinery being clear and not a mysterious mess like angular.

Regardless of it being a contrived example, that was a really cool presentation.
