DataWeave Function Definition Syntax

To define a function in DataWeave use the following syntax: fun myFunction(param1, param2, …) = <code to execute> The fun keyword starts the definition of a function.

myFunction is the name you define for the function.

Function names must be valid identifiers.

(param1, param2, …, paramn) represents the parameters that your function accepts. You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses.

The = sign marks the beginning of the code block to execute when the function is called.

<code to execute> represents the actual code that you define for your function.
