x-data assignment, is object or function?

[ericxin1982]

Hi,

I have a general question, somewhere I saw example x-data = {}, somewhere I saw example x-data=variable, and variable = (x) => ({}) defined in script section, and I am not sure when I should use {}, when I should use function, or I can just use function always.

Thanks for help me clarify this.
Thanks

If you are passing it to Alpine.data it must be a function that returns an object

When writing it in x-data, it needs to be an expression that evaluates to an object or to a function that returns an object.

All Alpine expressions are encapsulated into functions already.
