The problem is Datastar is actually a backend agnostic backend framework with a 10 Kb shim. There has never been anything like it in practice. So it is hard to explain.

# Learn Some Templating System:
|
||||
<div class="mt-10"/>
|
||||
|
||||
| Concept | Example | Meaning |
|
||||
| ----------------- | ---------------------------------------- | -------------------------- |
|
||||
| **Interpolation** | `{{ name }}` | Insert value of `name` |
|
||||
| **Loop** | `{% for item in items %}...{% endfor %}` | Repeat block for each item |
|
||||
| **Condition** | `{% if logged_in %}Welcome{% endif %}` | Conditional rendering |
|
||||
| **Include** | `{% include 'header.html' %}` | Reuse a subtemplate |
|
||||
| **Escaping** | `{{{ raw_html }}}` or `{{& raw_html}}` | Control HTML escaping |

# Templating and Hypermedia:
|
||||
<div class="mt-10"/>
|
||||
|
||||
| | Templating | Hypermedia as the Engine of Application State |
|
||||
| --------- | ------------------------ | ------------------------------------------ |
|
||||
| Input | Data | Data + available transitions |
|
||||
| Output | Document (HTML) | Document representing a state with actions |
|
||||
| Function | Bind data to structure | Bind state transitions to structure |
|
||||
| Goal | Present information | Drive navigation and state evolution |
|
||||
| Mechanism | Placeholder substitution | Link/form embedding |
|
||||
| Example | `{{.Title}}` → “Article” | `<a href="{{.Links.Edit}}">Edit</a>` |
