javascript - 如何通过 Lodash 将对象数组转换为一个对象

Question

示例:

[
    {"name":"tony", "age":14},
    {"name":"jacky", "age":23},
    {"name":"lucy", "age":34},
    {"name":"sam", "age":15},
    {"name":"jay", "age":31}
]

到:

{
    "tony": [],
    "jacky": [],
    "lucy": [],
    "sam": [],
    "jay": []
}

Answer 1

不需要使用Lodash。 Array.prototype.reduce()将完成这项工作。

const data = [
    {"name":"tony", "age":14},
    {"name":"jacky", "age":23},
    {"name":"lucy", "age":34},
    {"name":"sam", "age":15},
    {"name":"jay", "age":31}
];

const result = data.reduce((acc, curr) => {
  acc[curr.name] = [];
  
  return acc;
}, {});

console.log(result);
