Now we need to build a visitor. This code approximates the if statements we had in the preceding code:

varSelectiveNamePrinterVisitor = (function () { function SelectiveNamePrinterVisitor() { } SelectiveNamePrinterVisitor.prototype.Visit = function (memberOfArmy) { if (memberOfArmy._type == "Knight") { this.VisitKnight(memberOfArmy); } else { console.log("Not a knight"); } }; SelectiveNamePrinterVisitor.prototype.VisitKnight = function (memberOfArmy) { memberOfArmy.printName(); }; return SelectiveNamePrinterVisitor; })();
