Quote: backbone.js vs. knockout.js

Addy Osmani:

"To conclude, I personally find KnockoutJS more suitable for smaller applications whilst Backbone’s feature set really shines when building anything non-trivial. That said, many developers have used both frameworks to write applications of varying complexity and I recommend trying out both at a smaller scale before making a decision on which might work best for your Project."
