When I see such libraries, I would like to quickly understand if I am a potential user.

Instead of telling me the lib is great, things like the ones below are more useful:

You use moment.js? Mylib.js has better support for time parsing. Example :...

You use vuejs? Mylib.js does not require blah and the binding uses standard foo to do bar. Example :...

Etc. The author knows what others are using so pointing out how his lib is better (or positively different) compared to the others would actually be helpful
