 This is definitely the most difficult page in the guide to write, but we do feel it's important. Odds are, you've had problems you tried to solve and you've used another library to solve them.

If we didn't believe that, we wouldn't be working on it. We do want to be fair and accurate though. Where other libraries offer significant advantages, such as React's vast ecosystem of alternative renderers or Knockout's browser support down to IE6, we try to list these as well.
