====== Java Script Named Parameters In Functions ======

To use named parameters, we can pass an object to a function and then access the properties of that object within the function.\\ 
This approach makes the code more readable and allows you to easily pass multiple parameters to a function, including optional parameters with default values:

<code javascript>
function bookHotel({ city, nights, isBreakfastIncluded = false }) {
  if (!city || !nights) {
    console.log('Please specify the city and the number of nights.');
    return;
  }

  console.log(`Booking a hotel in ${city} for ${nights} nights.`);
  if (isBreakfastIncluded) {
    console.log('Breakfast is included.');
  }
}

bookHotel({ city: 'Paris', nights: 3, isBreakfastIncluded: true });
// Booking a hotel in Paris for 3 nights.
// Breakfast is included.

bookHotel({ city: 'London', nights: 2 });
// Booking a hotel in London for 2 nights.

bookHotel({ city: 'New York' });
// Please specify the city and the number of nights.

</code>

By using destructuring syntax within the function signature, you can specify the expected named parameters, and also provide default values for them.

<note>
This pattern is becoming increasingly common in modern JavaScript code, especially when you have a function that might accept **numerous parameters**, some of which are optional. It can make the code more self-documenting and help avoid errors that might arise from passing parameters in the wrong order.
