Add week 2 "Real world fetch" workshop

[oliverjam]

https://github.com/oliverjam/real-world-fetch

• Covers stuff you need to use fetch in a real app
  • Error handling for non-200 HTTP responses
  • fetch options:
    • method
    • body
• Handling user input with forms
  • preventDefault()
  • Various ways to access form input data

I'm not sure if it needs a proper "workshop" bit at the end. Some of the interspersed "challenges" are more involved and are basically what I'd want from a "workshop" anyway.

I also swapped the first-class functions and learn-fetch-promises workshops around, since we should cover callbacks before promises.

Closes #35

I ran through this and I think it's really good. I think you're right that the challenges throughout are involved enough to make this feel like a workshop with enough chances for students to practice the concepts that are covered for themselves 👍

[Albadylic]

Think this is a great resource. I think the challenges are at a good level that we don't need to add a workshop section.

I only have one edit to suggest which is a pedantic one again 🤓 . If you Ctrl + F in the readme "and use", I think these words can be removed.

[Albadylic]

p.s. I definitely learnt a couple of things from reading this!

[oliverjam]

@Albadylic cheers, fixed that bit. I think it could still do with a "workshop" part at the end because this is supposed to fill 2 hours. It's currently a 5 or 6 minute read (obviously longer with all the breaks to do the code challenges/let stuff sink in). It would be nice for people who have done some fetch before and whizz through the simpler parts to be able to push themselves a bit.

[Albadylic]

@oliverjam Yeah, I reckon this would benefit from a workshop section to fill the two hours. It could be very similar to the challenges, as in the learn-fetch workshop, but on a new api - something that is likely to 404.

[oliverjam]

@Albadylic I've added a simple-ish workshop at the end using the same PokéAPI they used in the first fetch workshop. This time they actually have to make a form and render to the page, plus handle errors.

[Albadylic]

Anytime you use the PokeAPI, you get my automatic approval.
