Template engines

Template engines are tools used in web development to generate dynamic web pages. They allow developers to create a basic structure (template) for a page with placeholders for variable content. When a user requests the page, the engine fills in those placeholders with real data—such as user information or product details—producing a complete, customized webpage. This separates the design (layout) from the data, making it easier to maintain and update websites efficiently. Think of it like a mold that shapes different content into the same layout, saving time and ensuring consistency.
