Eventonica Updates

[dpenny]

updating some of the tutorials after seeing people go through Eventonica last week:

• more detailed walkthrough for the getUsers endpoint - add information about the req.body, using postman, and naming

  • I want to encourage people to use Postman, since it can make debugging easier, and is a good skill for API development

• an example of useReducer where multiple fields are updated by one action

  • I feel like complex updating of state is one of the main benefits of useReducer -- the tutorial currently only shows one field at a time, so add another section about this

• make mock event IDs be strings, not int

  • saw some issues where people were confused because the input sends back an ID as a string, but the event IDs are stored as numbers. I feel like this was an unnecessary hurdle, and making them strings will make things flow smoother
