The JS minification preserve the operational qualities of the code while reducing its overall byte footprint.
Compression can dramatically reduce your page's size and thereby increase its speed. Minify your script to knock off 50 - 70% from your HTML, JS, and CSS files!
Minification is the method of reducing the web pages and script files with code and markings. It is one of the key strategies used in websites to minimise load times and usage of bandwidths. Minification significantly increases site speed and usability, translating directly into a better user experience. It's also useful for users who access your website with a restricted data plan and want to save on their usage of bandwidth when browsing the web.
This decreases the script size by deleting or minifying code in your scripts. By getting smaller JS scripts and files, your visitors can load your web pages more easily because they need to download less data while loading your web pages.
