prefer-global-this

📝 Prefer globalThis over window, self, and global.

💼 This rule is enabled in the following configs: ✅ recommended, ☑️ unopinionated.

🔧 This rule is automatically fixable by the --fix CLI option.

This rule will enforce the use of globalThis over window, self, and global.

However, there are several exceptions that remain permitted:

1. Certain window-specific APIs, such as window.innerHeight
2. Window-specific events, such as window.addEventListener('resize')
3. Computed property access on window, such as window[foo]

The complete list of permitted APIs can be found in the rule's source code.
