[TYPO3-ect] Evaluation: Which JS library to recommend?

[Elmar Hinz]

Hello all,

dispite of many drawbacks and tears in the past JS libraries are en vogue
again. Still impressive short term successes may be followed by
unsatisfied, complaining customers few monthes later, when the next
generation of browsers is comming up or when the fashion changes and
another champion is the new must have.  

However, a lot of progress has been made, long term stability is growing and
features have become that impressive, that you will often decide to use a
JS library especially to build applications in closed areas of your site,
that don't need to match standards of accessibility.

But it is a critical effort to give recommendations in this field by the
Extension Coordination Team. On the other hand the volatility is the reason
why TYPO3 extension developers expect some recommonendations, to get at
least a minimum of orientation for the usage within TYPO3 extensions.  

If we give a recommandation of a preferred JS library, which one should it
be today?
