Can it help with complex data transformation?

Yes, it implements functional patterns like map, filter, and reduce to create readable, declarative, and efficient data processing pipelines.

Does it support asynchronous error handling?

Absolutely. It provides patterns for robust error handling using try/catch blocks with async/await and Promise combinators like allSettled and any.

Is this skill useful for both frontend and backend JS?

Yes, the patterns provided are standard JavaScript features that work across Node.js environments and modern web browsers.

Can this skill help migrate my old JavaScript code?

Yes, it is specifically designed to refactor legacy JavaScript syntax into modern ES6+ features like arrow functions, template literals, and classes.
