This article is great intro.

Notes

• 127.0.0.1 is localhost.

• Can go to Network tab to see details about requests and why they failed if they did fail. Can view headers etc

• Web browsers will try to connect over port 80 by default.

• [Best way to poll REST API? Timer seems fine. If the data is really changing frequently a WebSocket seems more appropriate.

  If it’s changing infrequently but you wanna know right away, a silent push notification is the “right” way but that requires some infrastructure](https://twitter.com/_dte/status/1265606739564662785)
