JavaScript создать новый массив из существующего путем фильтрации значения объекта

Question

Я пытаюсь создать новый массив из существующего массива, фильтруя объект массива, только если value.added === true AND value.SP.type === 2 witch JavaScript функция, полезная для быстрого создания нового массива из существующего массива с cat_id и rm_id ? У меня есть объект с большим числом в массиве, который пытается ускорить возможную функцию ведьмы, которую я использую?

Это существующий массив

[
  {
    "cat_id": 38,
    "rm_id": 1,
    "items": {
      "Box": [
        [

Я пытаюсь создать новый массив из существующего массива, как этот вывод

[

    "parent_name": "Box",
    "child_name": "Big",
    "category_name": "Box",
    "SP": {
      "id": 203,
      "type": 2,
      "price": 15
    },
    "added": true
  },
  {
    "cat_id": 37,
    "rm_id": 1,

    "child_name": "Big",
    "category_name": "Box",

Вот частично полный ответ, если кто-то хочет его sh закончить. Он не объединяет внешние свойства, и есть несколько вложенных круглых объектов
