Reactive Properties

Reactive properties can be assigned to an element by using the add-property! function. Its first argument is the property name and the second argument is its default value (required). Optionally you can add an options map with the following keys:

• :type: a function that will transform the value to the expected type. By default it is js/String, but if, for example, your value needs to be a number, then you can override it with js/Number.
• :attribute: the attribute name (string) that maps to the property. By default it's the lower-case property name. E.g. a property someValue would map to an attribute somevalue. If you don't want the property to map to an attribute, you can assign false to it.

Example:

(-> (create-ce)
    (add-property! "count" 0 {:type js/Number})
    (add-property! "name" "")
    (define! "my-element"))
