Share a small js framework written by others

It mainly integrates common extensions, including Dom and String, Array, StringBuffer, and NameSpace. Of course Ajax is indispensable. The size is about 8 KB. Because the volume is strictly controlled, the function is limited. If you only need the Ajax part, it will be 1 K.

This small framework has been applied to the company's projects and began to gradually replace prototype. js on the front-end display page. We will make some applications around this framework in the future.
