How it works:

• Detects links within the viewport (using Intersection Observer)
• Waits until the browser is idle (using requestIdleCallback)
• Checks if the user isn’t on a slow connection (using navigator.connection.effectiveType) or has data-saver enabled (using navigator.connection.saveData)
• Prefetches URLs to the links (using or XHR). Provides some control over the request priority (can switch to fetch() if supported).
