Why Minify JS Code? (Why Use JS Minifier?)

JavaScript (JS) is the code that makes your website interactive, creating things like animations, pop-ups, and forms. Because this code can be complex and long, minifying it is a powerful way to speed up your site. Our JS minifier shrinks the code by shortening **variable names** and taking out extra characters, making it much smaller and faster for a browser to process. The result is a more responsive website, which is essential for a good user experience and better performance in search engines.
