Sample text

So, until that event fires, the application’s data may be in an inconsistent state. There’s no easy solution to the problem of bindings across evented models. In Backbone, a prudent way to step around the issue is the silent flag. If you add {silent: true} to a set event, no change event will happen. So, if several entangled models need to be updated at once, a good approach is to set them silently. Then call their change methods to fire the appropriate events only after they’re in a consistent state.

Normally, a Node app will exit immediately on an uncaught exception. But as long as at least one uncaughtException handler exists, the app will simply return to the event queue. error(err); // shutdown averted! 4, uncaughtException is deprecated. According to the docs,8 uncaughtException is a very crude mechanism for exception handling and may be removed in the future… Don’t use it, use domains instead. What are domains? you ask. Domains are evented objects that convert throws into 'error' events.

But the biggest gains from MVC happen when change events bubble up the data tree. Instead of subscribing to events on every leaf, you can just subscribe to the roots and branches. 4. info report erratum • discuss Evented Models • 25 Set/Get on Evented Models JavaScript as we know it doesn’t have a mechanism for firing an event every time an object is modified. So, for evented models to work, we have to remember to use methods like Backbone’s set and get. get('font'); // // // // // triggers alert!
