This is not "universal-router" issue.
See https://facebook.github.io/react/blog/2016/01/12/discontinuing-ie8-support.html

How to fix this?
Ans.: downgrade react version.

@Bogdaan
I have already switched to react v0.14. And if I comment out universal-router codes, the app works, if I kept, app breaks...

Could it be a babel polyfill issue or it doesn't support ES3?

I am still looking into this...

[kongliangyu]

It's actually an issue from babel runtime polyfill, see: babel/babel#3445
