Retrieving HTML templates asynchronously
The final step to mastering client-side templating is a development practice that allows us to load templates dynamically and use them in a web page that has already been loaded. This approach can lead to more scalable implementations than the approach of embedding all the available templates as <script> tags inside the HTML source of each page.
The key element of this technique is to load each template only when it is required for the presentation of a web page, commonly after a user action. The main benefits of this approach are that:
