Javascript Merge multiple object values into array

Question

I have an array that looks something like this:

[ { Id:1, Name:'' }, { Id:2, Name:'' }, { Id:2, Name:'' } ]

I want a result object that looks like this:

{ Id:[1, 2, 3] }

How do I achieve this in Javascript?

Answer 1

const array = [ { Id:1, Name:'' }, { Id:2, Name:'' }, { Id:2, Name:'' } ];
console.log({Id: array.map(element => element.Id)})

Answer 2

You can create an Object Literal and use Array.prototype.map() to get ids array to fulfill the Id property.

Code:

 const data = [ { Id: 1, Name:'' }, { Id: 2, Name:'' }, { Id: 3, Name:'' } ] const result = { Id: data.map(obj => obj.Id) }; console.log(result);

Answer 3

Try this:

var arr = [ { Id:1, Name:'' }, { Id:2, Name:'' }, { Id:2, Name:'' } ]
var Ids = arr.map(function(param){
return param.Id
});
var obj = {Id: Ids}
