Can someone explain how the datasets are matched together.
You have a list of counties and a list of zip codes?? (“fips”) whatever that means.
Peaking at the solution I can see this is how it was matched but I don’t understand it
let result = education.filter((obj) => obj.fips == d.id);
The counties dataset doesn’t have an id property as far as I can tell so result is always null.
My attempt is here
FIPS are the Federal Information Processing Standard Publication codes.
