I found an interesting thing in V8 engine when I was testing underscore.js library.
For arrays, the > for (var i = 0; i < len; i++) implementation can ran 24700 ops(operations per second), while the native function > Array.prototype.forEach only got 14200 ops. Then I tried IE10, in which the `nativeForEach` can reach a number of 43500. I checked the source code of V8 engine, but could not find out why this native forEach function is so slow. Can anybody explain this?
