Can this skill help migrate from ES5 to ES6+?

Yes, it is specifically designed to identify legacy patterns like var declarations and traditional function syntax, replacing them with modern equivalents like const/let, arrow functions, and template literals.

How does this skill improve code maintainability?

By promoting functional programming principles, immutability, and clean object literals, it helps reduce side effects and creates more predictable, testable code.

Is this skill relevant for Node.js developers?

Yes, the patterns provided are environment-agnostic and apply equally well to frontend browser development and backend Node.js or Deno applications.

Does it support advanced asynchronous programming?

Absolutely. It provides patterns for Promises, Async/Await, and advanced combinators like Promise.allSettled and Promise.any to handle complex concurrency effectively.
