Templating (EJS/Pug)

In short

Server-side templating engines that let Express render dynamic HTML pages directly from the backend — less common now with API + frontend-framework architectures, but still used for emails and simple server-rendered apps.

How to learn this

1Render a dynamic page with EJS, passing data from a route handler.
2Build an HTML email template using a templating engine.
3Understand why most modern apps separate the API from HTML rendering with a frontend framework instead.
