Concatenate multiple objects into one using Javascript

javascript Share on :

If you have multiple objects and you want to combine them into single object in Javascript then you can use below code.

const user = {
    name: 'John Deo',
    gender: 'Male'
};
const role = {
    admin: '1'
};
const details = {
    email: '[email protected]',
    city: 'New York',
};

const final_object = { ...user, ...role, ...details };

console.log(final_object);

We have three objects user, role, details and we want to make a final object from these three object. We are assigning the combination of these objects to final_object constant.
