Have you worked with Lighthouse? Suppose you are tasked with improving the FCP (First Contentful Paint) metric. What ideas come to mind?

To improve the FCP (First Contentful Paint) metric in Lighthouse, the following approaches can be applied:

• Optimize the loading of critical CSS and JS: minimize and defer the loading of non-essential scripts and styles so that the browser can render the first content faster.
• Use lazy loading for images and heavy resources: load them only when needed.
• Minimize server response time: speed up the backend, use CDN for static assets.
• Preload key resources using <link rel="preload">.
• Optimize fonts: use font-display: swap so that text is displayed immediately with a system font, then the custom font loads.

Example of using preload:

<link rel="preload" href="/styles/main.css" as="style">
<link rel="preload" href="/scripts/main.js" as="script">

These measures will help the browser render the first visible content faster, improving FCP.
