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);
