Function Elements

Function 

Functions are elements that define an expression, which can be used inside expressions across the entire WebVision project. Each function contains a script that is executed every time the function is invoked. 

• Script is a JavaScript code that can receive parameters through an array called “argv”.
• Script can be accessed from any other input in the project using the expression =func(“name”, parameter1, parameter2, …, parameterN).
