Maybe an oversimplified example may help:

const positionInWeek = (dayOfWeek) => {
  switch (dayOfWeek) {
    case "Monday":
    case "Tuesday":
      return "Start of the week"
    case "Wednesday":
    case "Thursday":
    case "Friday":
      return "Middle of the week"
    case "Saturday":
    case "Sunday":
      return "End of the week"
    default:
      throw new Error("Not a week day")
  }
}

This would be harder to understand in an object or if-else-if-chain.
