Templating Engines
Templating engines are software tools that generate dynamic content by combining static templates with data. They separate presentation logic from business logic, allowing developers to embed variables, loops, and conditionals into markup files like HTML, XML, or text. This enables the creation of reusable templates that can be populated with data from databases or APIs to produce final output.
Developers should use templating engines when building web applications, generating reports, or creating dynamic documents to avoid code duplication and improve maintainability. They are essential for server-side rendering in frameworks like Express.js with EJS or Django with Jinja2, and for client-side rendering in libraries like Handlebars.js or Mustache. Templating engines streamline development by enabling clean separation between data and UI, reducing errors and speeding up iteration.
