React components are solving issues they had with nested views.\n+\n+## Moving From Backbone To React\n+\n+[Clay Allsopp](http:\/\/twitter.com\/clayallsopp) successfuly ported [Propeller](http:\/\/usepropeller.com\/blog\/posts\/from-backbone-to-react\/), a fairly big, interaction-heavy JavaScript app, to React.\n+\n+> [

](http:\/\/usepropeller.com\/blog\/posts\/from-backbone-to-react\/)Subviews involve a lot of easy-to-forget boilerplate that Backbone (by design) doesn't automate. Libraries like Backbone.Marionette offer more abstractions to make view nesting easier, but they're all limited by the fact that Backbone delegates how and went view-document attachment occurs to the application code.\n+>\n+> React, on the other hand, manages the DOM and only exposes real nodes at select points in its API. The \"elements\" you code in React are actually objects which wrap DOM nodes, not the actual objects which get inserted into the DOM. Internally, React converts those abstractions into actual DOMElements and fills out the document accordingly. [...]\n+>\n+> We moved about 20 different Backbone view classes to React over the past few weeks, including the live-preview pane that you see in our little iOS demo. Most importantly, it's allowed us to put energy into making each component work great on its own, instead of spending extra cycles to ensure they function in unison. For that reason, we think React is a more scalable way to build view-intensive apps than Backbone alone, and it doesn't require you to drop-everything-and-refactor like a move to Ember or Angular would demand.\n+>\n+> [Read the full post...](http:\/\/usepropeller.com\/blog\/posts\/from-backbone-to-react\/)\n+\n+## Grunt Task for JSX\n+\n+[Eric Clemmons](http:\/\/ericclemmons.github.io\/) wrote a task for [Grunt](http:\/\/gruntjs.com\/) that applies the JSX transformation to your Javascript files.

Our views are represented as a tree - the subviews are children of CommentCollectionView - and they end up as part of a tree in the DOM. But there's a Handlebars layer in the middle (which deals in flat strings), so the hierarchy must be destructed and rebuilt when we render.\n+>\n+> What does it take to render a collection view? In the Backbone\/Handlebars view of the world you have to render the template (with stubs), render each subview which replaces a stub, and keep a reference to each subview (or anything within the view that could change in the future).\n+>\n+> So while our view is conceptually hierarchical, due to the fact that it has to go through a flat textual representation, we need to do a lot of extra work to reassemble that structure after rendering.\n+>\n+> [Read the full post...](http:\/\/joelburget.com\/react\/)\n+\n+## JSRomandie Meetup\n+\n+[Renault John Lecoultre](https:\/\/twitter.com\/renajohn\/) did a React introduction talk at a JS meetup called [JS Romandie](https:\/\/twitter.com\/jsromandie) last week.\n+\n+
