How does this skill help with legacy code refactoring?

The skill identifies outdated patterns such as callback nesting and var-based declarations, automatically suggesting modern equivalents like Async/Await, let/const, and arrow functions for better scoping and readability.

Does it support advanced functional programming?

Absolutely. It includes patterns for higher-order functions, currying, memoization, and partial application to help you write more declarative and reusable code.

Can it help improve JavaScript performance?

Yes, it provides patterns for optimized data processing using modern array methods and efficient asynchronous execution models (parallel vs. sequential) to reduce execution time.

Is this skill relevant for both Node.js and Browser environments?

Yes, the patterns provided—including ES Modules, Promises, and ES6 syntax—are foundational to modern JavaScript development across all runtimes.
