Google will index sites that render their pages through Javascript. There are two caveats to be aware of: 1. It drops out if it takes more than 5 seconds to complete its operation and uses whatever is render then. 2. Indexing with HTML happens in near-realtime. Indexing with JS to HTML is delayed by about 1-5 days depending on the popularity of the site. So if you're serious about it; you ought to heavily include metadata for Google to index during the first run through or place a bare bones HTML copy down.
