Modern JavaScript Patterns

What it does

When installed, the agent follows modern JavaScript conventions (ES6+ syntax such as async/await, destructuring, arrow functions, modules, and functional patterns) when writing or refactoring JavaScript. It applies a checklist of best practices, like preferring const, using optional chaining and nullish coalescing, and avoiding data mutation, and can consult reference documents for deeper examples and common pitfalls. It does not run code or access outside services by itself.

Try asking

• “Refactor this callback-based Node.js file to use async/await and modern syntax”Copy
• “Review my JavaScript module and suggest modern patterns like destructuring and optional chaining”Copy
• “Explain how to avoid mutating data in this reducer using spread operators and array methods”Copy
• “Show me common async pitfalls like promise anti-patterns in my code”Copy

Get better results

• Point the agent at a specific file or function so it can apply the patterns to real code rather than giving generic advice.
• Ask it to explain why each change is made if you are learning, since the guidance includes reasoning behind best practices.
• Review its refactors with your test suite, because syntax changes can alter behavior (for example, around this binding or error handling).
