JS Advanced: Airport Control Tower 🛫

Picture an airport coordinating dozens of flights.

• Design patterns are standard operating procedures ensuring every plane (feature) takes off safely.
• Observer pattern is the announcement system broadcasting gate changes to all passengers.
• Strategy pattern is choosing different landing approaches depending on weather.
• Singletons are the single control tower headset—only one at a time to prevent mixed signals.
• Memory management is clearing unused runways and hangars so new jets can arrive without delays.

When the control tower applies the right patterns and keeps resources tidy, flights stay on schedule—just like advanced JavaScript apps delivering smooth user experiences.
