Performance Analyzer

What is this warning?

An important script on your page could benefit from a preload hint. Preloading allows the browser to start downloading the script earlier in the page load process, ensuring it's available when needed and reducing the time to interactive.

How to Fix This Issue

How to Fix It

The Problem

A critical JavaScript file is discovered late in the loading process, delaying interactivity.

The Solution

Add a preload link in the `<head>` section for important scripts that are needed early.

<link rel="preload" href="/js/important-script.js" as="script">

Why This Works

Preloading critical scripts ensures they start downloading early, reducing the time between when they're needed and when they're available, which improves overall page performance and user experience.
