What does ‘using’ declaration in TypeScript 5.2 (Explicit Resource Management) provide?

Accepted Answer

The 'using' declaration in TypeScript 5.2 provides automatic resource cleanup by calling the Symbol.dispose method when the variable goes out of scope. This ensures deterministic cleanup of resources, making memory management more efficient.
