Can TypeScript Truly Enforce Private Member Access Restrictions?

Accessing TypeScript Private Members: A Deeper Dive

TypeScript's implementation of private members has raised questions among developers due to its seemingly inconsistent behavior. While code within the class cannot access private members, JavaScript code can.

Question:
Can TypeScript truly prevent access to private members outside of the class?

Answer:
No, TypeScript only enforces member privacy within the compiler. Private properties are implemented as regular properties, accessible to code outside the class.

Understanding Privacy Implementation:
TypeScript relies on the JavaScript interpreter to execute code, which does not natively support private members. Therefore, TypeScript's privacy enforcement is limited to the compiler.

Achieving True Privacy:
To ensure complete privacy within a class, consider using local variables within function scopes instead of class members. This approach prevents access using the this keyword and effectively isolates the data.
