In this lesson we'll look at hashHistory which uses a hash hack to track our route changes vs browserHistory which delivers clean urls, but requires server work to implement.
Using hashHistory:
<Router history={hashHistory}>
http://localhost:3333/#/contact?_k=0lz6yy
Using browserHistory:
<Router history={browserHistory}>
We still need server everytime to return us index.html
http://localhost:3333/contact
