Я хочу взять ключ fields и свойства из , включая> Актив и поместить их в правильные item> fields> picture с соответствующим ASSETID . Тогда включает будет просто удалено из всего этого, потому что оно больше не нужно.

Вот какой конечный результат мне нужен:

Что В настоящее время у меня есть функция, которая перебирает каждый элемент в items и пытается выяснить, содержит ли массив Assets ASSETID из элемента. 

const items = data.items.slice(0);
const assets = data.includes.Asset.slice(0);

items.forEach(item => {
  if (item.fields.picture !== undefined) {
    const {
      id
    } = item.fields.picture.sys;
    const mappedAssets = assets.map(asset => asset.sys.id);

    if (mappedAssets.includes(id)) {
      console.log('This id matched:', id)
    }
  }
})

const items = data.items.slice(0);
const assets = data.includes.Asset.slice(0);

items.forEach(item => {
  if (item.fields.picture !== undefined) {
    const {
      id
    } = item.fields.picture.sys;
    const mappedAssets = assets.map(asset => asset.sys.id);

    if (mappedAssets.includes(id)) {
      console.log('This id matched:', id)
    }
  }
})

Я не уверен, как распределить свойства так, как я хочу. Я двигаюсь в правильном направлении или я размышляю?

Решение в итоге получилось: 

    data.items.forEach(item => {
      if (item.fields.picture !== undefined) {
        const { id } = item.fields.picture.sys;
        const foundAssets = data.includes.Asset.find(asset => asset.sys.id === id);
        item.fields.picture = { ...item.fields.picture, fields: {...foundAssets.fields} };
      }
    });
    delete data.includes;

Я думаю, можно просто использовать forEach, выполнить сопоставление, распространить то, что требуется, и удалить то, что не требуется. Как то так
