Is it possible to assign the rest of the unstructured values ​​to a new object without creating a new key?

  • 772

I am performing the destructuring of an object, to make a new object that will have most of the values.

example:

const test = {
    a:'a',
    b:'b',
    c:'c',
    array:[
        {ar1:'1',ar2:'2'},
        {ar1:'2',ar2:'3'}
    ]
};
const {array,a, ...rest} = test;
const newObjet = {newData:array[0], rest};
console.log(newObjet);

As in the new object ( newObjet) I am not interested in what it has aand arrayit was done that way, so far so good.

The problem is that I don't want a key to be created reston the new object. The result I want is similar to the following:

{
  newData: {
    "ar1": "1",
    "ar2": "2"
  },
   b: "b",
   c: "c"
}

    Just do:

    const newObjet = {newData:array[0], ...rest};

    This way you also unstructure the rest object and it does not remain as a new property

    const test = {
    a:'a',
    b:'b',
    c:'c',
    array:[
        {ar1:'1',ar2:'2'},
        {ar1:'2',ar2:'3'}
    ]
};
const {array,a, ...rest} = test;
const newObjet = {newData:array[0], ...rest};
console.log(newObjet);
