To handle errors in async/await code, reject promises with real Error objects and handle rejections explicitly. This approach ensures consistent error semantics and prevents subtle bugs in your asynchronous control flow.

A terminating await is an unnecessary await at the end of a function. You avoid it by adding async only when awaiting is necessary and returning the Promise directly, which maintains correct promise usage without delaying execution.

To run promises in parallel in JavaScript, use Promise.all for concurrent tasks. This balances parallel versus sequential awaits, allowing multiple tasks to execute concurrently while maintaining readable error semantics.

Mixing promise styles causes bugs because it creates confusing control flow and inconsistent error handling. Standardizing on native Promises and consistent async/await patterns improves code reliability and maintainability.

Yes, these promise patterns apply to both frontend and backend TypeScript projects. The guidelines ensure correct promise usage, prevent anti-patterns, and improve reliability across any JavaScript or TypeScript environment.
