Description

This plugin provides Modernization rules — prefer modern ES idioms over legacy patterns.

Philosophy

Interlace fosters strength through integration. Instead of stacking isolated rules, we interlace security directly into your workflow to create a resilient fabric of code. We believe tools should guide rather than gatekeep, providing educational feedback that strengthens the developer with every interaction.

⚙️ Configuration Presets

🏢 Usage Example

// eslint.config.js
import modernization from 'eslint-plugin-modernization';

export default [
  modernization.configs.recommended,

  // Or be strict about modernization
  // modernization.configs.strict,
];

Why These Rules?

no-instanceof-array

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

// ❌ Bad: Fails across realms
if (value instanceof Array) {
}

// ✅ Good: Works everywhere
if (Array.isArray(value)) {
}

prefer-at

Array.at() provides cleaner negative index access (ES2022+).

// ❌ Bad: Verbose negative index access
const last = arr[arr.length - 1];

// ✅ Good: Clean ES2022+ syntax
const last = arr.at(-1);

prefer-event-target

EventTarget is the native browser API and doesn't require Node.js polyfills.

// ❌ Bad: Requires polyfill in browsers
import { EventEmitter } from 'events';

// ✅ Good: Native browser API
const target = new EventTarget();

📦 Compatibility

See the ESLint Version Support Policy — current ecosystem share data, the 20% gate, and the forward-looking exception that covers v10.
