There are some data types in appian like "User or Group", "Document or Folder" etc., You will not know exactly what value the variable has during process execution. It can be user or it can be a group, ex: it can hold "testUser" or "[Group:51]". 

We cannot find it out using typeof(), as it will return as "User or Group". So to specifically know what value the variable is holding during runtime we use runtimetypeof().

    typeOf(): 

    • It can retrieve the type of an expression during design time.
    • what the designer expects the data to be based on the configured type.
    • you can use this to validate or debug the expected type of an expression

    runtimetypeof():

    • it can retrieve the type of an expression during runtime of the that expression.
    • it says what the data is at runtime.
    • You can dynamically validate the type at runtime and handle unexpected data

      typeof():

      • Tells you the expected type of a value during design time.
      • If you want to check if a variable should be a "User" or "Group", typeof() will tell you it is "User or Group", but not the exact value.

      runtimetypeof():

      • Tells you the actual type of a value during runtime.
      • It shows the exact type at that moment, so you know if the value is a "User" (e.g., "test user") or a "Group" (e.g., "[Group:10]").
