Which specific ECMAScript features are supported?

The skill covers a wide range of features from ES6 through ES2022, including destructuring, spread/rest operators, template literals, top-level await, and advanced array methods.

How does it optimize asynchronous operations?

It provides patterns for error handling with try/catch in async functions and teaches the use of Promise combinators like Promise.allSettled and Promise.any for better concurrency management.

Does it include functional programming patterns?

Absolutely. It provides specialized guidance on pure functions, higher-order functions, currying, and memoization to help create more predictable and testable code.

How does this skill help with legacy JavaScript refactoring?

It identifies outdated patterns like callback hell or global variable declarations and provides automated suggestions to upgrade them to modern ES6+ equivalents like Async/Await and block-scoped variables.

Can I use this for both frontend and backend development?

Yes, these patterns are universal to modern JavaScript environments including Node.js and major frontend frameworks like React, Vue, and Angular.
