video 1.1 fetch() notes

[shiffman]

Filing some notes in case I want to record an extra video to go in between 1.1 and 1.2.

• mentioning try/catch as error handling option next step
• pointing out that this is just to demo fetch() of course just say <img src="rainbow.jpg">
• Noting that if you use return in getData() it’ll come back in the promise as response.

Also noting from @joeyklee (and this came in via YouTube comments as well)

• Since fetch() returns a promise either way is fine, but maybe future examples could introduce the try/catch block?
