JavaScript Advanced Internals

Use When

• Advanced JavaScript internals: closures, prototype chain, OOP with classes, functional programming patterns, memory management, event loop mechanics, and performance optimization. Use when implementing complex JavaScript features, debugging...
• The task needs reusable judgment, domain constraints, or a proven workflow rather than ad hoc advice.

Do Not Use When

• The task is unrelated to javascript-advanced or would be better handled by a more specific companion skill.
• The request only needs a trivial answer and none of this skill's constraints or references materially help.

Required Inputs

• Gather relevant project context, constraints, and the concrete problem to solve.
• Confirm the desired deliverable: design, code, review, migration plan, audit, or documentation.
