想請問如何把這個array修改成下面那個object
小弟本來想用forEach然後把name的value放到object裡當key使用
但是好像沒辦法

const personArray = [
        { name: "Kyle", age: 25, female: "man" },
        { name: "Helen", age: 18, female: "woman" },
        { name: "Ray", age: 33, female: "man" },
 ];

修改成

const personObh = {
        Kyle: { age: 25, female: "man" },
        Helen: { age: 18, female: "woman" },
        Ray: { age: 33, female: "man" },
 };

最佳解答

const personArray = [
        { name: "Kyle", age: 25, female: "man" },
        { name: "Helen", age: 18, female: "woman" },
        { name: "Ray", age: 33, female: "man" },
 ];


const resultObject = {};
for(let person of personArray) {
    resultObject[person.name] = person;
}

console.log(resultObject);

const personArray = [
        { name: "Kyle", age: 25, female: "man" },
        { name: "Helen", age: 18, female: "woman" },
        { name: "Ray", age: 33, female: "man" },
 ];

const resultObject = personArray.reduce((obj,person) => {
    obj[person.name] = person;
    return obj;
}, {})


console.log(resultObject);

Object.assign({}, ['a','b','c']); // {0:"a", 1:"b", 2:"c"}

const personArray = [
	{ name: "Kyle", age: 25, female: "man" },
	{ name: "Helen", age: 18, female: "woman" },
	{ name: "Ray", age: 33, female: "man" },
];
 
const personObh = personArray.reduce((obj, p)=>
	Object.assign(obj, {
		[p.name]: {
		age: p.age,
		female:p.female
	}})
,{})
