The modified answer address two issues with IE.<\/p>\n

    \n
  1. IE does not support arrow functions<\/li>\n
  2. IE does not support the spread operator<\/li>\n<\/ol>\n

    So the logic is pretty simple. If the make key is not in the result, put a new empty array in the result for the key. And then just push the value to it.<\/p>\n<\/p>\n

    var cars = [{\r\n    make: \"audi\",\r\n    model: \"r8\",\r\n    year: \"2012\"\r\n  },\r\n  {\r\n    make: \"audi\",\r\n    model: \"rs5\",\r\n    year: \"2013\"\r\n  },\r\n  {\r\n    make: \"ford\",\r\n    model: \"mustang\",\r\n    year: \"2012\"\r\n  },\r\n  {\r\n    make: \"ford\",\r\n    model: \"fusion\",\r\n    year: \"2015\"\r\n  },\r\n  {\r\n    make: \"kia\",\r\n    model: \"optima\",\r\n    year: \"2012\"\r\n  }\r\n];\r\nvar group = cars.reduce(function(r, a) {\r\n  r[a.make] = (r[a.make] || []);\r\n  r[a.make].push(a);\r\n  return r;\r\n}, {});\r\n\r\nconsole.log(group);<\/code><\/pre>\n<\/div>\n<\/div><\/div>\n
