The function is executed when the option is parsed. It is similar to the reviver parameter of the `JSON.parse()` function. This is the right place where you can validate the input data and `fail()` if it's not valid. For example, if the option requires a number you can validate the range here.

```javascript
.option ({ long: "name", metavar: "STR", reviver: function (value){
.option ({ long: "name", metavar: "STR", reviver: function (value, option){
return value + "bar";
}})
