Factory & Constructor Functions

What is the primary benefit of this mixin factory pattern?

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

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

const createEntity = (name) => {
  const base = { name };
  return withValidation(withLogging(base));
};

It improves performance
It creates immutable objects
It allows for flexible composition of behaviors
This mixin factory pattern demonstrates composition over inheritance by allowing flexible combination of behaviors (logging and validation) with the base object. Each mixin factory (withLogging, withValidation) adds specific functionality while maintaining object composition. This approach is more flexible than classical inheritance as it allows for picking and choosing which behaviors to include without creating deep inheritance hierarchies.
It reduces memory usage
