Async/await and Promises manage asynchronous programming in JavaScript by pausing execution until operations resolve. This Skill provides guidance on implementing these patterns to handle complex asynchronous workflows and write maintainable code effectively.

The best functional programming patterns for clean JavaScript involve array methods, higher-order functions, and immutability. This Skill explains how to utilize composition and these paradigms to create predictable, efficient, and maintainable codebases.

Refactoring legacy JavaScript to modern ES6+ syntax involves applying arrow functions, destructuring, spread/rest operators, and template literals. This Skill helps developers transition older codebases to clean, efficient, and maintainable modern standards.

You do not strictly need iterators and generators to build maintainable ES6 applications, but they are covered as modern features. Understanding them alongside class syntax and modules allows you to write more efficient and customized iteration logic.

Modern JavaScript Promises replace traditional callbacks by chaining asynchronous operations without nesting. This Skill distinguishes these approaches, demonstrating how Promises and async/await prevent callback hell and yield predictable execution.
