Map.prototype.forEach()
※ Download: Object keys foreach
Objects don't need a. I'll look at updating it, some time tonight.
These also work on objects, which is really neat. For example, it's much faster search an object for a key than it is to search an array for value presence.

This is not possible in ES5 thus not possible in node. We will get this eventually. The only solution is finding a node module that extends V8 to implement iterators and probably generators. I couldn't find any implementation. You can look at the spidermonkey source code and try writing it in C++ as a V8 extension. You could try the following, however it will also load all the keys into memory Object. As you can see Object. Whether the actual memory storage is more optimum is a different matter. It will list all or search for a specific item and then drill down by a given depth if need be. Perhaps you can customize this to fit your needs. I like to see the scope start AND end!!!
This algorithm is exactly the one specified in ECMA-262, 5th edition, assuming and have their original values and that callback. Objects don't need a. Whether the actual memory storage is more optimum is a different matter. If you'd like to contribute to the interactive examples project, please clone and send us a pull request. The ordering of the properties is the same as that given by looping over the properties of the object manually. Items on the prototype chain are not listed: function ParentClass ParentClass. Initial talks of for. I couldn't find any implementation.
