What is the TypeScript ‘using’ declaration (Explicit Resource Management) and which symbol does it rely on?

Accepted Answer

The TypeScript 'using' declaration is a variable declaration that automatically invokes Symbol.dispose when the block scope exits, ensuring deterministic cleanup. This feature helps manage resources efficiently and avoid memory leaks.
