Why Template Engines are Used?
A template engine empowers the utilization of static template files within an application. During runtime, variables in the template file are substituted with actual values, and the template is converted into an HTML file transmitted to the client. This method simplifies the design of HTML pages.
These engines come into play when swiftly constructing web applications with distinct components. Templates facilitate the quick rendering of server-side data essential for the application. Components like body, navigation, footer, dashboard, etc., can be efficiently managed.
The adoption of template engines enhances developer productivity, concurrently enhancing readability and maintainability.
