Last year, its size is 1k which they are proud of. Now 2.5k which is 2.5 times of used to be. Just let me guess: this library will become double size to 5k next year this time.

Even jQuery is thinking how to reduce the file size by its team. This library increases its size like this much. Seriously?

Chinese who works at English company still can not use this library, because too many Chinese characters to work with others who did not understand Chinese.

This library is very good and comprehensive, if this library is really in English, I believe it will become a big thing.

You don't need jQuery if you have written better wrapped API library and have already attracted millions of developer to test your library.

For the eco-system point of view, jQuery have been tested in the widest markets for many many years. well written document, many online cases, many supporters, many bug reporters, high cover unit tests,good code quality and so on.

Using jQuery for project is smart move unless high performance requirement.
