A while back I used eval in a matrix multiplication routine, to make it accept matrices of arbitrary size and generate code to multiply them: https://github.com/rogual/mxd/blob/master/Matrix.js#L50 https://github.com/rogual/mxd/blob/master/Matrix.js#L50 It benchmarked pretty well back when I wrote it, though I haven't checked against current JS engines to see if it's still a performance win.
