JavaScript Idioms and Patterns

What problem does it solve?

This Skill prevents inconsistent or fragile JavaScript code by guiding AI agents to produce modern ES module style, predictable async logic, and clearer error handling.

Core Features & Use Cases

• ES modules over CommonJS: prefer import/export for contemporary JavaScript codebases.
• Robust async/await patterns: use async/await, Promise.all for parallel I/O, and avoid unhandled promise rejections.
• Safer maintainability conventions: enforce const defaults, discourage var, encourage destructuring, and require domain-specific error classes rather than vague errors.

Quick Start

Use the JavaScript idioms skill to rewrite a Node.js service so it follows ES module conventions, uses async/await with parallel I/O, and includes domain error classes for missing resources.
