To refactor legacy JavaScript callbacks to async/await, convert callback-heavy functions into Promises and use async/await syntax for robust asynchronous flows and improved error handling. Start by converting a small callback-based function and progressively refactor surrounding code.

Modern ES6+ patterns for maintainable JavaScript include arrow functions for safer this binding, destructuring for cleaner data handling, and modules for modular architecture. These patterns help write cleaner, safer, and more expressive code across web and Node.js projects.

Yes, you can use ES6 modules and classes for both web and Node.js projects to achieve modular architecture and encapsulation. These modern JavaScript patterns apply to refactoring, modular design, and asynchronous code across both environments.

The best way to handle asynchronous flows in JavaScript is using Promises, async/await, and generators. These modern ES6+ patterns provide robust asynchronous execution, improved error handling, and streaming data capabilities compared to legacy callbacks.

You should use destructuring and spread/rest operators in JavaScript for cleaner data handling and safer this binding. These ES6+ patterns replace legacy data extraction methods, making your code more expressive, readable, and maintainable across teams.
