Refactor callback-based JavaScript to async/await by replacing nested callbacks with Promises and using async functions to simplify asynchronous flows. Start by refactoring a small module to observe cleaner asynchronous control flow and improve readability.

Modern JavaScript patterns for refactoring legacy code utilize ES6+ features like arrow functions, destructuring, spread/rest, and classes. These patterns reduce technical debt, improve maintainability, and enable modular application architecture.

ES6 modules improve JavaScript application architecture by enabling robust modularization and encapsulation. They allow developers to import and export functionalities, making codebases scalable, maintainable, and easier to optimize.

Use iterators and generators in JavaScript when you need custom iteration behavior or to handle asynchronous data streams. They provide robust architecture options for processing sequences lazily and managing complex control flows.

Template literals and destructuring allow writing concise, expressive JavaScript by simplifying string interpolation and extracting object properties. They enhance code readability and reduce boilerplate when building ES6+ modules.

Promises simplify asynchronous flows in web applications by providing a cleaner alternative to nested callbacks. They enable sequential async operations, better error handling, and work with async/await to optimize web application performance.
