如何将数组转换为对象

Question

我想转此:

let myArray = [ {city: "NY"}, {status: 'full'} ];

对此:

let myObj = { city: "NY", status: 'full' };

我试过这个:

let newObj = {};
for (var i = 0; i < myArray.length; i++) {
  (function(x) {
    newObj = Object.assign(myArray[i]);
  })(i);
}

它将最后一对分配给对象

Answer 1

将数组传播到Object#assign:

const myArray = [ {city: "NY"}, {status: 'full'} ];

const myObj = Object.assign({}, ...myArray);

console.log(myObj);

注意:分配到空对象.如果省略空对象,原始数组的第一个元素将被突变(所有内容都将合并到其中).
