As you may know, a huge part of the world is using WordPress on a daily basis. Mostly because it’s just so easy to use it from the editor's point of view. Yet, in order to add any functionality, the popular way is to use plugins that are easy to install and often doesn’t require any development skills.
And although it seems tempting, we cannot really recommend using plugins too often, as they are the main reason, why your website slows down a lot.
On top of that, things are getting outdated quite fast in web development, so in order to scale, or make changes to your website, you may find yourself installing more and more plugins that will, sooner or later, cause huge performance and speed problems.
