How to update min.js file in WordPress

When you’re running a WordPress website, you want it to be as fast as possible. One way to speed up your site is to minify your CSS and JavaScript files. In this article, we will show you how to minify CSS and JavaScript files in WordPress.

What is Minification?

In computing, minification is the process of removing all unnecessary characters from code, without affecting its functionality. These unnecessary characters usually include white space characters, new line characters, comments, and block delimiters.

Minification can be done manually by a developer. However, there are many tools available that can automate the minification process.

Why Minify CSS and JavaScript Files?

When a browser loads a page, it has to download all the CSS and JavaScript files. By minifying these files, you can reduce the number of bytes that need to be transferred. This can speed up your page load times, and improve user experience.

In addition to reducing the size of files, minification also improves caching. When a browser downloads a minified file, it can cache that file. When a visitor goes to another page on your website, the browser can load the minified file from its cache instead of downloading it again.

If you have a lot of JavaScript and CSS files, then minifying all of them can have a significant impact on your page load times.

That being said, let’s take a look at how to minify CSS and JavaScript files in WordPress.

Don’t forget to click on the ‘Save Changes and Empty Cache’ button to store your settings.

You can now visit your website to see the changes. All your CSS and JavaScript files should now be minified.
