This function is for BASIC compatibility. It is not available in pure JavaScript projects.



VarType returns an integer that indicates the type of a variable. The required parameter, variable, is any variable that doesn't contain a user-defined type.

When variable is an array, the value returned is equal to the array constant plus the constant that specifies the element-type.
