UPJS is a javascript library that has a selector for the html elements and provides a better way of manipulation of the HTML elements. UPJS is composed of three seperate parts. The first one is core UPJS in which selector and basic HTML element manipulation implemented. The second part is extentions which provide additional capability on html elemenents or utility functions that are needed. The last but not the least is plugins which provide enrichment of the library in a standard way. From an architectural perspective, UPJS aims 3 layer approach. First layer is UPJS core functionalities, second for its extensions and last layer for its plugins.
UPJS development is stopped in 2010 due to the insane improvement in JQuery. :D As of 2017, it's just ancient :)
