Prefer More Precise Variants of any to Plain any

Overview

If you must use any, make it as specific as possible.

Plain any accepts everything. But any[], Record<string, any>, or () => any are narrower and still provide some type checking.

When to Use This Skill

• Forced to use any for some reason
• Writing functions that accept "anything"
• Dealing with truly dynamic data
• Migrating from JavaScript
