Hi ! Thanks for reading. :)
I can only hope that’s this is the fastest way to iterate. The solution to getting the best efficient way is to study the behavior of V8 Engine by analyzing code produced by the engine. I tried to get some information with this method, but it’s very hard because V8 is really big and complex engine.
My goal with this is article is to explain why the previous better solution was not so good now, and give a new way. If someone finds a new better way, I will be happy to link his article at the top of mine. But currently, that’s the faster way I found.
