Minify Javascript - What Is a Js Minifier Tool and Why do we need to Minify Js?

Javascript code is code that runs in the clients browser and can manipulate the DOM. With that kind of DOM manipulation, we can make a normal looking website highly interactive. Now if you are starting out and creating Javascript code for a new website, the JS code and file would be very small, may be in bytes. But as soon as your website grows to a big organizational level website, the Javascript code get's huge. The JS files may be in hundreds of Kilobytes. When a website loads it pulls the Javascript files over the internet.

If the size of the Javascript file is small, the loading would not take much time and the website will load quickly, but if the size of the Javascript code is bigger, the website may be slower to load depending on the spped of the internet of the user.

In order to decrease the size of these Js files, we follow a process called Js Minification or Javascript minification. Minifying Javascript code files would mean to keep all the code intact, still reducing the size of the files by removing all the white spaces from the JS code. When we minify javascript files, we greatly reduce the size of the js file and thereby decreasing the website loading time.

The below image shows you the difference in size between an unminified javascript file and a js minified file.
