Refactoring legacy JavaScript to ES6+ involves replacing callback structures with async/await, applying destructuring for variable extraction, and using arrow functions to improve code readability and maintainability.

JavaScript optimization for functional programming involves using iterators and generators to handle data streams efficiently, alongside adopting modern patterns for clean, error-handled code that boosts application performance.

Async/await modernizes asynchronous JavaScript by allowing developers to write promise-based asynchronous code that reads top-to-bottom like synchronous code, simplifying error handling and making complex asynchronous flows more maintainable.

Yes, using modern JavaScript patterns requires an existing understanding of ES6+ syntax and functional programming concepts to effectively implement iterators, generators, and class features within your applications.

Use iterators and generators in JavaScript applications when you need to handle large data streams or infinite sequences efficiently, enabling custom iteration logic while optimizing performance and memory usage.
