Asynchronous behavior, part 1

Follow-ups from last week:

1. Putting data on the map

   • Working with SDP school list data

     • Think of schools as a table: a collection of records that all have the same fields (attributes), but with different values.
     • JavaScript is not like R or Pandas; can think of schools like a table, but can't treat it like one.

   • JS isn't built around tables.

     • Arrays are important!
     • Objects are important!
     • Functions are important!

   • Let's work with a real data set

     • You've already contributed to a dataset (class dossier -- open the console and inspect the people variable)
     • We'll explore some information about schools in Philadelphia
       • A couple sources: OpenDataPhilly, or the School District of Philadelphia
       • Browsing data in the console
       • Counting data
       • Iterating over data (but why 🤔?)
       • Transforming data (e.g., plucking attributes, reshaping)
       • Aggregating data (e.g. counteach, ...)
       • Filtering data
       • Sorting data
2. Introducing form elements
3. Laying out a page
   • The CSS box model, flex box, grid
   • Manipulating styles in the developer tools
     • Let's have a bit of fun with https://www.nytimes.com/interactive/2022/09/09/climate/growing-wildfire-risk-homes.html

Next steps:

1. Responding to interaction
   • On the map
   • Through form elements
2. Manipulating the DOM
   • The what? (basically, the HTML document structure)
