Scripting doubt: data.get(xx)

[Luiz Lucena]

Hello friends, 

I'm still crawling in JavaScript, JSON, etc...

When working on a workflow, I saw this:

var vResult = data.get(18).result;
var vErrorMessage = data.get(18).message;
current.work_notes = "Mule REST Service Faile. ERROR: " + vErrorMessage;

My doubt is, where that number comes from?

If I need to change anything on the workflow, would affect that?
That workflow calls an Activity that integrates with Mulesoft to assing Oracle Responsibility.

Thanks in advance,
