Definitions and usages
The element is used to declare local or global variables.
Note: If declared as a top-level element, it is a global variable. If you declare a variable within a template, it is a local variable.
Note: Once you set the value of a variable, you cannot change or modify it!
Tip: You can add values to variables by the contents of the element or through the select property!
