How do ES2025 features like using and Promise.try() enhance JavaScript coding patterns?

ES2025 introduces features like using for scoped resource management and Promise.try() for safer asynchronous error handling, streamlining common coding patterns.

The using statement ensures automatic cleanup of resources after use, improving memory safety. Promise.try() wraps synchronous code into promises with proper error capturing, enhancing async code reliability.

Code

using file = openFile('data.txt');
console.log(await file.read());

Promise.try(() => riskyOperation())
  .then(result => console.log(result))
  .catch(error => console.error(error));
