Description: The template engine is responsible for rendering templates and generating HTML responses in web applications. This system allows developers to separate application logic from presentation, thus facilitating code maintenance and scalability. Templates use a specific markup language that allows dynamic content insertion into HTML, such as variables and control structures. This means developers can create dynamic web pages that respond to user interactions and server data. Additionally, many template engines are highly extensible, allowing developers to create their own custom tags and filters. Key features include template inheritance, which allows code reuse and the creation of consistent design structures, and the use of blocks, which facilitates the customization of specific sections of a template. In summary, a template engine is a fundamental tool that enhances the creation of robust and efficient web applications while improving the developer experience by providing an intuitive and flexible environment for generating dynamic content.
