通过遍历数组合并一些对象

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: ""
}
]

我尝试了以下方法，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);
