Knockout is simple, declarative, lightweight, and fast. It's an MVVM data binding library, not a framework and it does its job very well. I enjoy the push to separate concerns and make the UI data driven. It's a very active open source project and has greate browser compatibility. Review collected by and hosted on G2.com.

With simplicity you get what you signed up for. I don't really dislike anything about knockout itself, but some people may see the fact that you will need other libraries/frameworks to build an enterprise server side data driven application. Review collected by and hosted on G2.com.

Annoying to wrap all types in ko.observable.

No idea how to use with ES6

Data binding probably too complicated for large app

Error in binding syntax difficult to debug

React's single direction data flow easier to understand Review collected by and hosted on G2.com.

Data binding is really nice. Knockout components are awesome. Review collected by and hosted on G2.com.

It's not really a framework so there's no defined coding patterns you have to follow. It's easy to do the same thing quite differently. Review collected by and hosted on G2.com.
