I am welcome back to you. No chance with you. I promise that we would have a look at the different templating engines. And I'm going to start with Jade, which is the default engine that shipped with our boilerplate. Here, basically, we set up and I want to introduce you to that language, how it works, or how does the templating engine work and how we can create our HTML files with it and output dynamically. Let's start. I open the layout Dutch shade file in our fuse folder and this is the kind of route layout that our Earth use is extending. And here's the first feature, we can well extend layouts and insert content dynamically. So, here for example, in the layout, the shape while providing a basic skeleton for all our layouts, this is a basic HTML document skeleton and there we can anomalously enter the specific content of our other layouts. We'll get back to this a second because now you might wonder this is our HTML skeleton, it doesn't really look like HTML right? That's one of the most important things about Jade, we don't use the standard HTML tags there but we use indentation to structure our document. So, the tag names are the same, we have our doctype HTML at the beginning but in a normal HTML, we would have like divs right? This is how it is written. A normal HTML type element and yeah document our HTML element might look like this and also, we would have closing tags. We don't have to, in Shade, we don't have the smaller and greater signs to create our tags which has tag names and we use indentation to make clear in which level we are currently at and how we nest elements.
