• Poll schema uses string for results, how could we improve on this? Also the following request allows me to completely change the results

curl -H 'Content-Type: application/json' -X PUT -d '{ "results":  ["32", "2", "5", "0"] }' http://localhost:9000/api/polls/556c8129bf64e30727806aeb

• socket io is used but the poll is updated not real time. Suppose I vote and leave the tab open with the results. The results should get updated as others are voting. What steps would be taken in order to push updates?
• Were there any challenges in putting the project together?
• What would you change or improve on? What other things would you like to work on if you had more time?

In many websites, there are static portions of the page such as the navigation or header that rarely change. If we could deliver the markup for navigation, the experience would feel a bit snappier while the rest of the page is generated.

Try running this snippet in node and visit localhost:3000/incremental and localhost:3000/blocking. These are pretty trivial examples but we could cache and immediately send the nagivation bar and `` elements for every request.

// not tail call optimized
(def! fact (fn* (x) (if (= x 0) 1 (* x (fact (- x 1) )) )))

// tail call opt
(def! fact-tail (fn* [x accum] (if (= x 0) accum (fact-tail (- x 1) (* x accum)))))
(def! fact (fn* [x] (fact-tail x 1)) )

No formatting because... newlines mess up interpreter parsing.
