My experience with CGAL is that it's slow, clunky and very difficult to work with. I understand that it's the 'gold standard' of libraries but for the purpose I was using it for (2d polygon boolean operations, polygon offsetting), I found ClipperLib [1] to be far superior in terms of ease of use, stability and execution speed. There's even a JavaScript port of ClipperLib [2]. I highly recommend ClipperLib to anyone that only needs simple 2d polygon manipulation.
