Omit properties from an object

Here is a cool method for omitting properties from an object using the ES7 Object Spread Operator

We are destructuring the user object to store password and address inside a constant and then grabbing whatever remains into another constant labelled safeUser which has the password and address properties omitted 🤜🤛

With this pattern we aren't mutating or modifying the existing user object. We are removing the reference to certain properties.

const user = {
  id: 12345,
  password: "password123",
  address: "123 Ocean Drive",
  name: "Billy Ocean",
  age: 80,
  status: "Legend",
};

const { password, address, ...safeUser } = user;

console.log(safeUser);
// { id: 12345, name: 'Billy Ocean', age: 18, status: 'Legend' }
