Bind

Bind attributes are a category of attributes wrapped in square brackets, [], whose right hand side (the attributes' value) is a reactive value updating the "properties" of the Element (it may update a class, a property, an attribute, etc.).

The syntax looks like this:

<div
  [name]="$.source$"
></div>

When the Element is connected to the DOM, the reactive value is subscribed, and its incoming values will mutate the element's properties.
