Since we defined the `result` attribute in the `payload` variable, this information can be used later in other messages within the same automation — as shown in the example, where we have a final message to display the BMI calculation result to the client: Capturing with payload Capturing with payload This way, it is possible to incorporate the results of complex processes using **Execute JavaScript** in client-facing messages, ensuring a personalized and dynamic response — as in the example where the final message displays the calculated BMI result.
