FontAwesome is a popular icon set and toolkit used by web developers to add icons to their web pages. Loading the Font Awesome library can be a heavy process, and it can slow down the website's loading time. One solution to this problem is to lazy load the Font Awesome library using JavaScript. In this post, we'll show you how to do just that.

To lazy load the Font Awesome library, we'll be using a JavaScript function called "loadCSS." This function creates a new link element and appends it to the document's head. By setting the "media" attribute of the link to "only x," we prevent the browser from downloading the Font Awesome CSS file until it's necessary.

Here's the code that you can use to lazy load the Font Awesome library:

Here's a breakdown of how the code works:

• We define a function called "loadCSS" that takes three arguments: the URL of the CSS file, the element to insert the link before (optional), and the media type (optional).
• We create a new link element using the "createElement" method and set its "rel" attribute to "stylesheet."
• We set the "href" attribute of the link to the URL of the Font Awesome CSS file.
• We set the "media" attribute of the link to "only x," which means that the browser will only download the CSS file when it's necessary.
• We insert the link element into the document's head using the "insertBefore" method.
• We use the "setTimeout" method to set the "media" attribute of the link to "all" after a certain amount of time. This ensures that the Font Awesome icons will be visible on the page when they're needed.

And that's it! By lazy loading the Font Awesome library, you can improve your website's loading time and provide a better user experience for your visitors.
