 At Facebook, we support older browsers, including IE8. We've had polyfills in place for a long time to allow us to write forward-thinking JS. This means we don't have a bunch of hacks scattered throughout our codebase and we can still expect our code to "just work". For example, instead of seeing `+new Date()`, we can just write `Date.now()`. Since the open source React is the same as what we use internally, we've carried over this philosophy of using forward thinking JS.
 
-In addition to that philosophy, we've also taken the stance that we, as authors of a JS library, should not be shipping polyfills as a part of our library. If every library did this, there's a good chance you'd be sending down the same polyfill multiple times, which could be a sizable chunk of dead code. If your product needs to support older browsers, chances are you're already using something like [es5-shim](https://github.com/kriskowal/es5-shim).
