Just like CSS and HTML, minifying JavaScript can also provide performance benefits for your visitors. And obviously, speed is a huge factor for search engines, so any performance improvement with your JavaScript code is a step in the right direction for better visibility in page rankings as well. Besides just reducing the size of the JavaScript file, JavaScript minification also helps reduce the amount of bandwidth a site uses, improves script execution, and reduces the overall number of HTTP requests, which as we discussed earlier, helps reduce overall load to the server.
