The Javascript Clipper library performs clipping and offsetting for both lines and polygons. All four boolean clipping operations are supported - intersection, union, difference and exclusive-or. Polygons can be of any shape including self-intersecting polygons.

Javascript Clipper is a port of Angus Johnson's Clipper library: https://sourceforge.net/projects/polyclipping

    The most awesome JavaScript library for working with polygons there is. The demo page is very useful for testing functionality without having to set up any code. Thanks for sharing Timo.
