- Let's pretend for a second that this pplFromAPI array isn't hardcoded, and instead it's being returned to us depending on service calls elsewhere in our application.
- It's our job to transform this data into a 1dimensional array for the UI to iterate over and display accordingly.
- One way of implementing this is using .concat in conjunction with the ...spread operator introduced with the release of ES6.
Shields us having to iterate thru each nested array, building up the final value on each pass.
