Here are a few that I plan to look at in the nearest future:
- Angular – developed and maintained by google. Read some good reviews about it.
- Durandal – not sure how I stumbled upon that, but they do have a bold punch line – “Single page apps done right” – and just for that, it’s worth looking at
- Backbone – this I think is the second most popular one after knockout. It can be married with Marionette. From the reviews – quite powerful.
- Ember – an emerging new thing, very different from the rest, but…this guy is struggling with it (as you can see here and here) – so I’m afraid that it may be even more confusing to me. I’ll definitely give it a spin though – just because it’s so different, and it’s always worth to broaden up the view.
