To pass parameters with a template in ISML, which syntax should you use?

The correct choice utilizes an object notation to pass parameters when rendering a template with ISML (Interpreted Server Markup Language). In the syntax provided, ISML.renderTemplate('...', {ismlVarName: value}), the curly braces {} denote that parameters are being passed as key-value pairs within an object. This structure is essential because it allows for clear and organized handling of multiple parameters by naming them explicitly, which is particularly beneficial in a templating system where multiple values may need to be sent at once.

Using this method, the variable ismlVarName becomes accessible inside the ISML template, enabling dynamic content rendering based on the passed values. This approach promotes maintainability and clarity in code, as it separates the argument keys from their corresponding values, making it easier to manage and read.

The other options do not adhere to the proper object syntax required for passing parameters in ISML, leading to potential misinterpretations of how arguments are handled within the templating system.
