如何将每个对象插入密钥对值

Question

I have a object like where I declear some properties and value.

var obj = {
    "country" : "USA",
    "CApital" : "WDC",
    "President" : "Trump"
}

Now I am adding in this way, I make one id and in that id I want to add my object property and values.

var myId =  obj.President;

this.newObj[myId] = {};

Object.each(obj, function(key, value) {
    this.newObj[myId][key] = value;
});

My output shoud be

obj :{
    Trump :{
        "country" : "USA",
        "CApital" : "WDC",
        "President" : "Trump"
    }
}

Answer 1

There is no such thing as Object.each.

Simplest is use Object.assign() to merge copy of original object to new object

 let obj = { "country" : "USA", "CApital" : "WDC", "President" : "Trump" } let newObj= {[obj.President] : Object.assign({}, obj)} console.log(newObj) 

Answer 2

I understood you want to create a new object with a property value equals to source object identifier evaluation, and inside that property goes the initial object. Something like this:

 const obj = { country: 'usa', capital: 'dc', president: 'trump' }; function myPropAndObjectValues(obj, prop) { return { [obj[prop]]: {...obj} }; } console.log(myPropAndObjectValues(obj, 'president')); 

Pd. Object.each doesn't exist.
