Refactor callback-heavy code by replacing nested callbacks with arrow functions, async/await for asynchronous operations, and destructuring to simplify parameter handling. ES6+ patterns eliminate callback nesting, improve readability, and make data flows clearer in both web apps and Node.js projects.

Core ES6+ features include arrow functions, destructuring, spread/rest operators, template literals, modules, classes, and async/await. These features replace verbose syntax with concise, maintainable code and provide modern tooling support for refactoring legacy applications.

Async/await simplifies promise-based code by allowing synchronous-style syntax for asynchronous operations. Combined with promise chains and functional patterns, it handles robust data flows and eliminates callback pyramids common in legacy JavaScript.

Yes. Functional programming patterns—map, reduce, compose—express data transformations clearly and work seamlessly with ES6+ iterators and generators. These techniques improve code reusability and maintainability in modern JavaScript applications.

ES6 modules provide file-based code organization with explicit imports and exports, replacing older module patterns. Classes offer structured syntax for object-oriented designs. Together, they enable scalable, maintainable architecture across web and Node.js projects.

Iterators and generators enable lazy evaluation and efficient data processing for large datasets or infinite sequences. They work with functional patterns to create clean, memory-efficient transformations and are essential for advanced asynchronous workflows.
