Defining methodsSince a method is really a property which contains a function value, defining a method simplyconsists in defining a regular function, then assigning it to a property.For example, the following program adds a method start to the myCar object defined inthe previous section:function start_engine() {writeln("vroom vroom")}myCar.start = start_engineNow, the expression myCar.start() will call the function defined as start_engine.Note that the only reason for using a different name for the function and for the method is toavoid confusion; we could have written:function start() {writeln("vroom vroom")}myCar.start = startI L O G O P L D E V E L O P M E N T S T U D I O L A N G U A G ER E F E R E N C E M A N U A L245
