Intersection Observer & Efficient Scroll Handling

What is the significance of the time property in IntersectionObserverEntry?

const callback = (entries) => {
  entries.forEach(entry => {
    const timeSinceStart = entry.time - performance.now();
    if (entry.isIntersecting) {
      trackVisibility(entry.target, timeSinceStart);
    }
  });
};

It represents the page load time
It shows how long the element has been visible
It provides the timestamp when the intersection occurred
The time property in IntersectionObserverEntry represents the timestamp (in milliseconds) when the intersection was recorded. This is valuable for: 1) Calculating how long elements have been visible, 2) Implementing time-based visibility tracking for analytics, 3) Measuring scroll performance and user behavior, 4) Coordinating animations based on intersection timing. The timestamp is based on performance.now(), providing high-resolution timing information that can be used for precise measurements and optimizations.
It measures observer initialization time
