javascript - 将一组对象转换为一个对象对象

Question

如何将一组对象转换为一个对象对象。我的函数可以工作，但我不希望每个对象之前都有键名称。

 myArray = [{
     "name": "ann",
      "y": 191,
      "color": "red"
    },{
     "name": "mary",
      "y": 11,
      "color": "red"
    },{
     "name": "henry",
      "y": 11,
      "color": "red"
    }]

let result = {};
for (let item of seriesTotal) {
  result[item.name] = item;
delete item.name;
}   

我想要这个

myObject = {{
 "name": "ann",
  "y": 191,
  "color": "red"
},{
 "name": "mary",
  "y": 11,
  "color": "red"
},{
 "name": "henry",
  "y": 11,
  "color": "red"
}{

对象是属性的集合，属性是名称(或键)与值之间的关联。

您可以使用索引作为键或属性名称。使用Object.assign创建一个新对象。使用 map 和 spread 语法循环遍历数组。

let myArray = [{
  "name": "ann",
  "y": 191,
  "color": "red"
}, {
  "name": "mary",
  "y": 11,
  "color": "red"
}, {
  "name": "henry",
  "y": 11,
  "color": "red"
}];


let result = Object.assign(...myArray.map((o,i) => ({[i]: o})));

console.log(result);
