The main optimizations are - Removed visibleKeys - Removed proxy cache - Removed Object.assign - No key concatenating anymore - No key recalculating anymore - Improved indentation logic - Improved string escape logic - Added many fast paths - Optimized code branches a lot - Optimized (boxed) primitive handling - Inline code if possible - Only check extra keys if necessary - Guard against unnecessary more expensive calls This also fixes a bug with special array number keys as e.g. "00". Besides that there were lots of smaller optimizations, the code got a bit cleaned up and a few more tests got in.
