Share a small js framework written by others_javascript skills

It mainly integrates commonly used extensions, including Dom and String, Array, StringBuffer, NameSpace, etc., and of course Ajax is indispensable. Volume is about 8k. Because the volume is strictly controlled, the functionality is limited. If you only want the Ajax part, it's only 1k.

This small framework has been applied to the company's projects and has begun to gradually replace prototype.js on the front-end display page. Some applications will be made around this framework in the future.
