将数组转换为对象布尔值 [英] Convert an array into object boolean

问题描述

我有这个数组 [一个，两个，三个] 想要将其转换成这个 {one：true ，两个：true，三个：true} 。基本上，所做的就是将数组项转换为对象的键，并使它们为布尔值。我试过使用价差运算符 {... arr} ，结果为 {0：'one'，1：'two'，2：'三个'} ，有任何想法吗？

I have this array ["one","two","three"] would like to convert it into this {one:true, two:true, three:true}. Basically what am doing is converting the array items to keys of an object and make them boolean. I have tried using spread operator {... arr} which results to {0:'one',1:'two',2:'three'}, Any Ideas?

推荐答案

您可以映射对象并将它们分配给单个对象。

You could map objects and assign them to a single object.

var array = ["one", "two", "three"],
    object = Object.assign(...array.map(k => ({ [k]: true })));

console.log(object);
