Convert data formatted as a tabular array into an array of objects for easier use with D3

main.js

var table = [
  [“STATE”, “DATE”, “ANOTHERTHING”], // Header row
  [“ALABAMA”, “2000”, “MORESTUFF”],
  [“ALASKA”, “2000”, “OTHERSTUFF”]
];

var data = tableToArray(table[0], table.slice(1));

data[0] // {"STATE": "ALABAMA", "DATE": "2000", "ANOTHERTHING": "MORESTUFF"}
