Points To Note 

The following keywords are restricted to be saved in JavaScript :

• While using script conditions in URL Parameter, you must enter  the param value inside square brackets []. For example, application. survey.urlparam ["userName"] in JavaScript, because special characters are not allowed in the JSON key in dot notation.

• To avoid syntax errors, javascript code should contain javascript syntax, and it should always end either with a semicolon or be properly wrapped inside curly braces.

 Sample Reference 

A sample reference Java script snippet code to achieve a simple arithmetic  operation :

The given code combines arithmetic operations and conditional statements to make decisions based on the values of certain variables or expressions.

var rating = application.survey.question.C.response +           application.survey.question.D.response;

if (application.survey.question.A.response == "Single"

application.survey.question.B.response == 2)

{

    return true;

}
