Modern JavaScript Patterns

Comprehensive guide for mastering modern JavaScript (ES6+) features, functional programming patterns, and best practices for writing clean, maintainable, and performant code.

Use this skill when

• Refactoring legacy JavaScript to modern syntax
• Implementing functional programming patterns
• Optimizing JavaScript performance
• Writing maintainable and readable code
• Working with asynchronous operations
• Building modern web applications
• Migrating from callbacks to Promises/async-await
• Implementing data transformation pipelines

Do not use this skill when

• The task is unrelated to modern javascript patterns
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.
