How to copy some properties from an object in JavaScript?
To copy some properties from an object in JavaScript, we can use the destructuring syntax.
For instance, we write:
const user = {
id: 123,
firstName: 'John',
lastName: 'Smith'
};
const {
id,
...newUser
} = user;
console.log(newUser);
to get all properties from user except id and assign that to newUser with the destructuring syntax.
The ... operator returns an object with all the properties except for the ones that has already been destructured.
Therefore, newUser is {firstName: 'John', lastName: 'Smith'}.
Conclusion
