Dynamically constructing HTML responses at the edge based on request headers, such as Accept-Language, allows for personalized and efficient content delivery. This use case showcases how EdgeKV can be used to store and retrieve data at the edge, enhancing performance and reducing latency.

The Hello World example demonstrates how you can use EdgeWorkers and EdgeKV to implement a simple Dynamic Content Assembly use case whereby the HTML response is dynamically constructed on the edge based on the content of the Accept-Language header in the client request. It also shows how you could use the getText() helper method.
