Specific format using Javascript arrays (map)?

@Paul_Wilkins

var data = [data_1, data_2, data_3, data_4, data_5, data_6, data_7, data_8, data_9, data_10];
var title = [title_1, title_2, title_3, title_4, title_5, title_6, title_7, title_8, title_9, title_10];

var combined = data.map(function combineTitleData(dataItem, index) {
  return {
      title: title[index],
      data: dataItem
  };
}).filter(function removeEmpty(item) {
  return item.data.length;
});

Awesome, works like a chant. Thank you so much.
Just an optional question, what part of the code “formats” the order?

[{
  data: ["23", "11", "4", "77", "9", "123"],
  title: "Title_1"
}, {
  data: ["5", "4", "122", "41", "74", "61"],
  title: "Title_2"
}, {
  data: ["6", "55", "14", "12", "75", "9"],
  title: "Title_3"
}, {
  data: ["8", "5", "5", "3", "1", "7"],
  title: "Title_4"
}, {
  data: ["25", "63", "31", "53", "21", "64"],
  title: "Title_6"
}, {
  data: ["74", "41", "64", "51", "23", "36"],
  title: "Title_8"
}, {
  data: ["7", "75", "34", "99", "74", "15"],
  title: "Title_10"
}]

The result output adds the data then the title. If I wanted to change that to add first the title and then the data what I should change?

It’s not important and the code will work with this format, just want to know and understand better how the code works to learn from it.

Thank you sooooo much!
