Can it improve my application's performance?

By implementing parallel execution patterns with Promise.all and using optimized array methods, it helps reduce execution time and memory overhead.

Does this skill support the latest ECMAScript features?

Yes, it includes support for ES6 through ES2022+ features, including top-level await, Promise.allSettled, and enhanced object literals.

How does this skill help with legacy JavaScript refactoring?

The skill identifies outdated patterns such as callback nesting or 'var' declarations and automatically suggests modern equivalents like async/await, const/let, and arrow functions.

Is this skill useful for functional programming?

Absolutely. It provides patterns for higher-order functions, currying, memoization, and pure data transformations using map, filter, and reduce.
