Google Pagespeed: Reduce Unused JavaScript! (Solutions)

[Arron]

You can use your browser's developer tools to check your page's loading time and the size of JavaScript files, and identify and remove any unused code snippets.

However, if you frequently change a JavaScript file, caching it may slow down the page load time. In such cases, stopping caching of frequently used files can improve page load speed. Optimize JavaScript files. By optimizing your JavaScript files, you can reduce file size and speed up page loading times. There are many tools available for this purpose, typically compressing JavaScript files to reduce their size. Remove unnecessary JavaScript libraries. If you're not using all the features of a JavaScript library on your page, removing it can reduce file size. Use asynchronous or deferred loading.
