Modern Syntax Features

Master class instantiation with the new operator to create objects from ES6 classes for cleaner object-oriented JavaScript code.

Calculate property values dynamically with getters that compute results from other properties when accessed.

Control property access with getters and setters that look like regular properties but execute custom logic on access.

Enforce data integrity with setter validation that checks and sanitizes values before allowing property updates.
