Are you eager to enhance your website’s speed and provide a smoother user experience? Look no further! One of the most effective strategies to achieve this is by implementing lazy loading for all JavaScript files on your website.
JavaScript files are instrumental in driving the functionality and interactivity of your site. However, loading all these files simultaneously can severely hamper your site’s speed, particularly during times of heavy traffic.
In this blog post, we’ll guide you through the process of speeding up your website by adopting lazy loading for all JavaScript files, using a straightforward and user-friendly code snippet.
What is Lazy Loading?
Lazy loading is a smart technique designed to load assets like images and JavaScript files only when they’re actually needed. By doing so, it reduces the initial load time of your website, resulting in a significant improvement in site speed.
When it comes to JavaScript files specifically, lazy loading can work wonders for your site’s performance, especially if you’re dealing with numerous JavaScript files that require loading.
How to Lazy Load JavaScript Files
Implementing lazy loading for all JavaScript files on your site is simpler than you might think. You can achieve this by integrating the following code snippet:
function lazyOnload(){let e=document.createElement(“script”);e.src=”https://example.js”,e.async=!0,document.body.appendChild(e)}function Dtc(){lazyOnload(),localStorage.setItem(“lazyCheck”,”true”)}var lazyGetStorage=localStorage.getItem(“lazyCheck”);if(“true”!=lazyGetStorage){var e=!1,t=!1;window.addEventListener(“scroll”,()=>{(0!=document.documentElement.scrollTop&&!1===e||0!=document.body.scrollTop&&!1===e)&&(Dtc(),e=!0,t=!0)},!0),window.addEventListener(“click”,()=>{!1===t&&!1===t&&(Dtc(),t=!0,e=!0)},!0)}”true”===lazyGetStorage&&lazyOnload();
This code loads a global JavaScript file asynchronously, which helps to improve site speed. The code also includes a function called ‘Dtc‘ that sets a local storage value to ‘true‘ to prevent the code from running again if the user has already loaded the global JS file.
To add this code to your site, simply add it within the </body> tag.
Once you have added this code, all JavaScript files on your site will be lazy loaded, which will help to improve your site speed and enhance user experience.
So why wait? Give your website the speed boost it deserves with lazy loading today. Your users will thank you for it!
