The original title is about TypeScript's `using` keyword and Explicit Resource Management. Let me rewrite this for a mobile feed.

Short summary

TypeScript's `using` keyword implements the Explicit Resource Management proposal to automatically close resources when they leave scope, eliminating manual try-finally blocks and preventing leaks from database connections and file handles. The feature uses Symbol.dispose for synchronous cleanup and Symbol.asyncDispose for async operations, with TypeScript managing a disposal stack in reverse order. This language-level guarantee prevents the three most common leak patterns: early returns, thrown exceptions, and forgotten cleanup.

• •Using keyword automates resource cleanup when scope exits via Symbol.dispose/Symbol.asyncDispose
• •Prevents memory leaks from forgotten finally blocks and exception-unsafe manual cleanup
• •Handles multiple resources with automatic disposal stack in reverse order of acquisition
