I would like to add to the other comments, in that I had no idea what polyvalent meant too. I am going to make a wild guess in the dark here, and say that English isn't your first language (I sincerely apologize if I'm wrong). If this is true, did you try to translate a word from your native language into English, or are you a chemist ;) I know exactly what you're trying to say with the term, but I think you could have much better uptake of your software if you found a word which conveys what you want to convey to a programmer audience. After looking at the etymology of the word and your explanation of what it means, may I humbly put forward a couple of alternatives, and I am sure HN users could contribute more: Anime.js is a multi-target yet lightweight Javascript animation library. Anime.js is a flexible yet lightweight Javascript animation library. Anime.js is a multi-framework yet lightweight Javascript animation library. Anime.js is a polygamous yet lightweight (and STD free!) Javascript animation library. The last entry is a feeble attempt at humour. P.S. Great job on the library, especially keeping it lightweight
