Object Creation Methods

What composition pattern is shown here?

const withLogging = (target) => ({
  ...target,
  log(msg) { console.log(`[${target.name}]: ${msg}`); }
});

const withValidation = (target) => ({
  ...target,
  validate() { return typeof target.name === 'string'; }
});

const user = withValidation(withLogging({ name: 'John' }));

Classical Inheritance
