React Native Android Friendly

[brentkirkland]

For in loops break RN Android...
Was wondering your thoughts on making the for in loop a traditional loop
Seems like others experience similar issues.

Very interesting error with react native on android. And weird that they does not create a check for including Symbol polyfill on compilation/interpretation...
I have absolutely no opposition of using a traditional loop.
Will merge it, Thank you for your PR.

This will be deployed in the day on npm ;)

Yes very weird...
