Discussion on: Refactoring: My 6 favorite patterns

About #1, how do you implement "getUser(userData)"?

[Bryce]

I'd probably use a switch statement to instantiate the appropriate user type - so something like:

function getUser(userData) {
  const userType = userData.favorites.food;

  switch(userType) {
    case 'pizza':
      return new PizzaUser(userData);
    ... 
  }
}

You might have included this snippet in the article

This is like the #1 #1 part of the article... You might want to add it.

Switch statement itself sometime bound you, we can use factory pattern to return the desire class object ;)

[Bryce]

Thanks, Abdul. Could you provide an example of what the code might look like? Most factory functions I've seen still involve a switch statement or a series of if/else statements.
