Advanced Modifiers

Data Mapping using a second version of mapping method.
ADVANCED MODIFIERS
Advanced Modifiers indicate a secondary and more developer-friendly approach to modify data.
There are two accepted formats for using advanced modifiers:
  • Format 1 (Keyword arguments): Specifying parameter names while passing values
Example:
ARRAY_APPEND([1,2,3], element=5) (or)
ARRAY_APPEND(source=[1,2,3], element=5)
  • Format 2: Without mentioning parameter names
Example:
ARRAY_APPEND([1,2,3], 5)
Note:
String must be passed by enclosing the data in single or double quotes.
GROUP and EXPRESSION are deprecated.
