If you’ve been curious about the MV* Javascript frameworks that all the cool kids are fussing over, Marius Gundersen provides a succinct and valuable cross-section comparison between AngularJS, Ember.js and KnockoutJS.
Extracted from his presentation:
| AngularJS | Ember.js | KnockoutJS | |
|---|---|---|---|
| Binding | Dirty Checking | Explicit Observable | Explicit Observable |
| Rendering | Async | Async | Sync |
| Computed Properties | ✗ | ✓ | ✓ |
| Dynamic Dependencies | ✗ | ✗ | ✓ |
Some of Marius’ key takeways:
- Ember slowest at rendering lists.
- Anguler slowest when model is complex.
- Knockout slowest when pushing many items.
More importantly, I take this as a reverse pivot table exercise – see what features are being compared to figure out what they’re actually meant to be doing. Far more informative than “A framework for creating ambitious web applications” or “HTML enhanced for web apps!”.
