audit-performance

name	audit-performance
description	Use when the user wants to check if their JavaScript code is efficient, asks about Big-O complexity, suspects a memory leak, or notices slow performance. Analyses time/space complexity, identifies hidden bottlenecks, and provides an optimized version.
argument-hint	[paste your code or describe the performance concern]

Audit Performance Skill

Procedure:

1. Time Complexity: State the Big-O time and space complexity of the provided code.
2. Identify Bottlenecks: Point out any hidden performance traps (e.g., using delete on array indexes, creating closures inside loops, forced synchronous layouts in the DOM).
3. Optimize: Provide a highly optimized version of the code.
