2. Google can execute and follow several types of js redirects, and the result is similar to how a 301 updates the index and preserves rank.
3. Google can read the DOM and then index dynamically inserted content.
4. Google can read meta data inserted in the DOM, such as rel canonical tags, robots noindex tags, and meta descriptions. We even inserted structured data dynamically and it resulted in rich snippets in Google's SERP.
