This is a version of Curran's car report tutorial. The 'car' elements replaced by generic spreadsheet-familiar language.
This excersize helped me apply Curran's lesson to spreadsheet tables of my own data.
The original lesson can be found here 'https://youtu.be/_8V5o2UHG0E?t=6148'
'headers' in the data.js file are meant to imply the headers of a spreadsheet that organize a column of data.
each object in data.js can be thought of as a complete 'row' of this conceptual SS table.
