通过迭代数组来合并一些对象

Question

我有以下数组recipe = [{    id: "abc123", en: {title: "", description: ""}, es: {titleES: "", descriptionES: ""}},{    id: "abc128", en: {title: "", description: ""}, es: {titleES: "", descriptionES: ""}},{    id: "abc135", en: {title: "", description: ""}, es: {titleES: "", descriptionES: ""}}]我想创建一个包含 1 个对象的新数组，其中包含对象“id”和“en”，如下所示newArray = [{    id: "abc123", title: "", description: ""},{    id: "abc128", title: "", description: ""},{    id: "abc135", title: "", description: ""}]我尝试了以下操作，但似乎无法正常工作const dataList = [];      for (let idx in recipe) {                dataList.push({...recipe[idx].id, ...recipeES[idx].all });              }

使用数组映射方法遍历数组并创建对象。

const recipe = [

  {

    id: 'abc123',

    en: { title: '', description: '' },

    es: { titleES: '', descriptionES: '' },

  },

  {

    id: 'abc128',

    en: { title: '', description: '' },

    es: { titleES: '', descriptionES: '' },

  },

  {

    id: 'abc135',

    en: { title: '', description: '' },

    es: { titleES: '', descriptionES: '' },

  },

];

const ret = recipe.map((x) => {

  const obj = { id: x.id, ...x.en };

  return obj;

});

console.log(ret);
