The maker pattern in JavaScript works by creating a function that, in turn, creates objects. This pattern is also known as the factory function pattern. Here’s a simple example:

const createUser = (firstName, lastName, city) => {
  return {
    firstName: firstName,
    lastName: lastName,
    city: city,
  };
};

This is very useful and often better than constructor functions for several reasons:

1. Avoids Boilerplate Code: Constructor functions require the use of the this keyword, which can be verbose and sometimes confusing for new developers.

2. Simplicity: The implementation is clean and easy to follow. You can quickly see the structure of the object being created.

3. No new Keyword: Unlike constructor functions, you don’t need to use the new keyword to create an instance.
