Destructure an object to remove a property link

Use case link

I want to delete a property from an object in a pure (immutable) way.

Use a destructuring assignment to assign the to be removed property to a variable, while cloning the "rest" properties to a new variable. The _ is used to prevent a linter giving the warning "variable is declared but its value is never read".


 
const { password: _, ...user } = {
  id: 47,
  username: 'tim',
  password: 'iliketrains',
};
 
console.log(user);
// |> { id: 47, username: 'tim' }
