I am trying to update an Object key using destructuring like this

let user = {
    name: "raju",
    age: 40,
    sex: "male"
}

name = "vvvv"

user1 = {name, ...user}

console.log(user1)

But it is not updating name == 'vvvv' in user1.

I am confused, need some help on this.

Later property names will overwrite earlier property names. Just like a duplicate name below results in the last one being included in the object:

console.log({
  name: 'foo',
  name: 'bar'
});

When using spread syntax, you should put the properties you want to overwrite the others last:

user1 = {...user, name}

Order matters, you have to put the updated property at last position:

let user = {
    name: "raju",
    age: 40,
    sex: "male"
}

name = "vvvv"

user1 = {...user, name}

console.log(user1)
