A great way to increase the efficiency of our code is by externalizing and minimizing our code.
It’s very easy to do. You would just take everything inside the script tags, remove it, and then create a new text file with a .js extension. Then you would simply use a script tag to point to that file.
And then we can get rid of the script tags altogether by highlighting and deleting them.
But we can jump back over to our index.html. And then, after we’ve loaded all our dependencies, we’ll create our own script tag to load the file that we just created.
Now, how do you minify? There are several options.
Visual Studio Code Plugins
Keep in mind that after you minify your code, you need to change the file that you’re pointing to in the HTML file. So if you minified site.js, then you would have a new version probably called site.min.js. And so in your HTML, you would want to point to that minified version instead of the original version of your code. Otherwise, all that minification is pointless
If for some reason you just like using notepad to do all of your code editing, you can still minify, and one way you can do that is by going to a website like JSCompress.
The benefit to that is that if you’ve created your website in Texas and somebody in the UK wants to access your website, then without a CDN, that user would have to connect to your server in order to get all of the files they need.
Keep in mind that a CDN does cost money, so that’s really only something you want to pursue if you’re ready for that next level. But it really can help to speed up your website.
