To refactor JavaScript with async/await, you replace nested callback structures or raw promise chains with sequential try/catch blocks, ensuring robust error handling and improving code readability for maintainable applications.

Securing JavaScript applications involves implementing defenses against XSS and prototype pollution by validating inputs, avoiding unsafe object mutation, and following established security best practices to prevent common vulnerabilities.

Memoization and debouncing optimize JavaScript performance by caching expensive function results and limiting execution frequency, significantly reducing redundant computations and improving runtime efficiency.

Building robust JavaScript code requires leveraging ES6+ features like arrow functions, destructuring, and modern asynchronous patterns to create clean, maintainable, and production-ready application logic.

Yes, you can obtain a production-readiness checklist for JavaScript development that outlines testing strategies and addresses common pitfalls to ensure your application logic is robust before deployment.
