[Solved] Reduce Unused Javascript [100% Working Solutions ]

To reduce unused JavaScript and improve page speed, consider removing or deferring any code that is not essential for rendering or interactive user experience. This can be achieved through code splitting, lazy loading, and minification techniques. Additionally, consider using tools like Chrome DevTools or Lighthouse to identify and eliminate any unused code. Prioritizing critical rendering paths and minimizing browser-blocking resources will lead to faster loading times and a better user experience. Some general tips that may help in reducing the unused JavaScript on your website, according to Page Speed Insight:

1. Identify and Remove Unused JavaScript: Review your website's JavaScript code and try to identify any scripts that are not being used or are unnecessary. Remove these scripts from your website to decrease the overall size and complexity of your pages..

2. Minify Your JavaScript: Minification is the process of removing unnecessary characters, such as spaces and comments, from your JavaScript files. This can significantly reduce the size of your scripts, which can help to speed up page load times.

3. Use Lazy Loading: Lazy loading is a technique that defers the loading of non-critical resources, such as images and JavaScript, until they are needed. This can help to improve page load times and reduce the amount of unused JavaScript that needs to be loaded up-front.
