Typescript Tutorial #27 Getters & Setters Typescript
0In TypeScript, you can define special methods called getters and setters within a class to control the access and modification of class properties. Getters allow you to retrieve the value of a property, and setters allow you to set the value of a property with additional logic

Key points about getters and setters:
Getters are defined using the get keyword followed by a method name (e.g., get area()). They are accessed as properties, without parentheses.
Setters are defined using the set keyword followed by a method name (e.g., set diameter(d: number)). They are used to assign values using the = operator.
Getters and setters allow you to encapsulate logic related to property access and modification.
Getters and setters can have the same name as the property they correspond to (e.g., area getter for the area property).
While the example demonstrates using private properties, you can use getters and setters with any visibility modifier (private, protected, or public).
Getters and setters are powerful tools to maintain control over how properties are accessed and modified in your classes. They allow you to introduce validation, calculations, or side effects when dealing with properties, all while maintaining a clean and intuitive interface for external code.
