Can this skill help with JavaScript performance?

Yes, it includes patterns for memoization, efficient array methods, and non-blocking asynchronous execution that can significantly optimize runtime performance.

Does it support functional programming concepts?

Absolutely. It provides guidance on higher-order functions, currying, partial application, and using pure functions to create more predictable code.

How does this skill help with legacy code?

It identifies outdated syntax such as 'var' or callback-based asynchronous logic and provides modern alternatives like 'const/let', template literals, and async/await for better readability and safety.

Is it suitable for Node.js or browser-side development?

The skill focuses on core ECMAScript (ES6+) language features, making it highly applicable to both frontend browser environments and backend Node.js applications.
