如何按给定数量复制数组中的对象，ES6 及更高版本

我正在尝试转换一个对象数组，如果对象属性数量大于 1，我将返回重复的对象。

const objects = [
  { id: 1, name: "Scissor", price: 2, quantity: 3 },
  { id: 2, name: "Hat", price: 6.5, quantity: 1 },
  { id: 3, name: "Socks", price: 0.5, quantity: 5 },
];


// desired return
[
  { id: 1, name: "Scissor", price: 2 }
  { id: 1, name: "Scissor", price: 2 }
  { id: 1, name: "Scissor", price: 2 }
  { id: 2, name: "Hat", price: 6.5}
  { id: 3, name: "Socks", price: 0.5 }
  { id: 3, name: "Socks", price: 0.5 }
  { id: 3, name: "Socks", price: 0.5 }
  { id: 3, name: "Socks", price: 0.5 }
  { id: 3, name: "Socks", price: 0.5 }
]

My code:

const objects = [
  { id: 1, name: "Scissor", price: 2, quantity: 3 },
  { id: 2, name: "Hat", price: 6.5, quantity: 1 },
  { id: 3, name: "Socks", price: 0.5, quantity: 5 },
];

let newObjects= [];

Object.entries(objects).forEach(([key, value]) => {

    for (let i=0; i < value.quantity; i++){
        newObjects.push({ id: value.id, name: value.name, price: value.price})
    }

});
console.log(newObjects);

所以我上面的代码确实有效，确实返回了我想要的东西，但是我觉得有更好/更流畅和更多的 ES6 及更高版本的方法。有人可以建议更好的方法吗？

你可以使用.fill() and .flatMap().

const objects = [
  { id: 1, name: "Scissor", price: 2, quantity: 3 },
  { id: 2, name: "Hat", price: 6.5, quantity: 1 },
  { id: 3, name: "Socks", price: 0.5, quantity: 5 },
];
let newObjects = objects.flatMap(e=>
  Array(e.quantity).fill({id: e.id, name: e.name, price: e.price})
);
console.log(newObjects);
