HEEx is not HTML

Read time: 1 minute

Let me tell you a secret. Until now I kept calling the result of the render/1 function a HTML. The story isn't quite like that! sigil_H actually returns a data structure called HEEx. This structure is optimized to know when something has been modified based on its assigns and send the minimum amount of data from the server to the client.

How to pronounce HEEx?

The creator's official pronunciation is "hiccs" as can be seen in this video which introduces the structure.

In the next classes we will learn a little bit more about HEEx's super powers. In fact, you've already learned at least one: assigns are part of HEEx's range of features.
