You can use the Array.from method, which is being added in ES6, but only supports arrays and iterable objects like Maps and Sets (also coming in ES6). For regular objects, you can use Underscore's toArray method or lodash's toArray method, since both libraries actually have great support for objects, not just arrays. If you are already using underscore or lodash, then luckily they can handle the problem for you, alongside adding various functional concepts like map and reduce for your objects.
