As I said here the last time a new React version came out, we're using React for more or less all new JS development at Khan Academy, and we're loving it.

Happy to answer questions.

What does it give you above other frameworks, specifically Angular?

I wrote a little bit about my experiences here:

http://benalpert.com/2013/06/09/using-react-to-speed-up-khan...

In short, it's simple (very little to learn) and very fast. One other big thing I love is that it encourages building reusable and composable components. Angular has a lot of the same structure, but if you end up building directives then you have to drop down to manual DOM manipulation again if you want speed.

Any framework like React (which embeds html tightly with javascript) is flawed at its core.

HTML itself is declarative in nature. All frameworks should embrace this.

By looking at React docs, I can tell you from my experience that it'll be pain in the s to maintain a large scale React application.

AngularJs' declarative way gives an app maintainability and highly test-ability. These two things are not the luxury but a must have requirement for any large scale long-live application.

Here's my talk from JSConf EU that directly tackles those concerns. http://2013.jsconf.eu/speakers/pete-hunt-react-rethinking-be...

1) I totally disagree about embedding HTML, but it's optional anyway. Cohesion counts. See Pete Hunt's video.

2) React programs tend to be very "dearative" in my eyes. Any declarative language still needs abstraction facilities: ie functions.

3) you can trivially implement any "more declarative" model you want on top of React's stellar core.

4) all of the benefits of test ability from angular apply to react too

Sorry about typos, on phone

<tabManager background=blue> <tab closeButton=true> Hello {{propertyName}} </tab> </tabManager>

This is what you typically get at the end in an Angular app. You don't need to "figure out" things where they are and what they are, and what they do in DOM.

Show me this declarative thing in React.

And this is just one part of Angular.

With React, you get to choose the parts of your code that integrate tightly which each other. Choice is good.

And if you don't like html in js, you could always embed ClojureScript in ClojureScript :-):

The React devs are well aware of what they are doing, and argue that they are merely coupling technologies, not coupling design concerns:

Of course you're free to agree or disagree with their argument, but I wouldn't assume they are just newbs who are unaware of standard best practices. They know the "rules" and are breaking them consciously.

Damn, from misreading the headline I thought ReactOS had jumped up a few version numbers.

zpao• 13 years ago

Sorry to get your hopes up! I'll try to remember to make it a bit more obvious next time.

I just read through all the React docs and the tutorial. My first impression is it looks and reads like Flex for Javascript, both for the JSX markup and the component lifecycle events. I'm not saying that is a bad thing, just an observation.
