This makes sense because C++ will likely remain\n// faster than JS when doing raw CPU-intensive sorting. However, when using a\n// custom comparator function, calling back and forth between the VM's C++ and\n// JIT'd JS is rather slow *and* loses JIT type information, resulting in\n// worse generated code for the comparator function than would be optimal. In\n// fact, when sorting with a comparator, these costs outweigh the benefits of\n// sorting in C++.
