I got this scriptlet:

var myresults = new String();
var myresults = scriptletContext.get("results");
var resp = myresults.includes("True");
if ( resp ){
 scriptletResponse = "success";
}
else {
 scriptletResponse = "failure";
}

I'm trying to evaluate the response I get from an operation a string "True" or "False" ( that is filtered out of a XML response)

and I always get this error, the erro is always when using .includes() , it seems that the method is available.

I either need it to work or something that does the same ( return true/false when comparing 2 strings)
