javascript-development

What problem does it solve?

This skill provides a structured, consensus-driven approach to JavaScript development across Metalsmith plugins, browser scripts, and Node.js tooling, addressing inconsistencies that slow projects and complicate maintenance.

Core Features & Use Cases

• Functional-first patterns: Promote pure functions, immutability, and clear data flow to reduce bugs.
• ES6+ best practices: Guidance on modern syntax (const/let, destructuring, template literals, async/await).
• Documentation discipline: Use JSDoc for type hints and API clarity, with dual ESM/CJS module support for broad compatibility.
• Testing and tooling: Mocha-based testing patterns and a scalable project structure for plugin development, browser scripts, and Node build tasks.
• Use Case: Build a Metalsmith plugin that processes files with pure transformations, and test it with Mocha to ensure predictable results.

Quick Start

Install Node.js, initialize a Metalsmith project, and apply the described patterns to implement a simple plugin with unit tests.
