In most of cases we use only 10% of the functionality of jQuery while the whole jQuery library has a big size. To solve this problem jquip was introduced.
jquip
Smaller, Lighter, Faster, more modular jQuery – include only the parts you want. Don’t use it, Don’t include it.
The core jquip.js is only 4.28KB (minified and gzipped) only 13% of the size of jQuery.
Has 90% of the good parts of jQuery (rest to be added plugins as needed).
Most code has been ported from jQuery and optimized where possible. Some methods are only partially implemented.
