JavaScript小技巧

Quick Review

This skill provides basic JavaScript tricks including type conversion, IIFE, and closures. While the code examples are correct and the structure is clear, the description is minimal (just a source URL) making it unclear when/how a CLI agent should invoke this skill. The content is educational but consists of common JavaScript patterns that don't represent significant complexity or cost savings - a modern CLI agent can easily explain these concepts without this skill. The task knowledge is moderate with working examples but lacks depth, context for usage, or comprehensive coverage of JavaScript tips.
