Rules

Presets

• recommended - Balanced modernization for most projects
• strict - All rules as errors for aggressive modernization

Why These Rules?

no-instanceof-array

instanceof Array fails across different realms (iframes, workers). Array.isArray() is the correct, reliable check.

prefer-at

Array.at() provides cleaner negative index access and is part of ES2022. This rule helps migrate legacy arr[arr.length - 1] patterns.

prefer-event-target

EventTarget is the native browser API and doesn't require Node.js polyfills like EventEmitter. This rule helps migrate browser code to use native APIs.

Migration Path

These rules are designed for incremental adoption:

1. Start with recommended preset (warnings)
2. Fix violations as warnings appear
3. Graduate to strict preset when ready
