How to set default value for Function object?

Question

Is there a better way to add a default value to a Function object?

 function CountOfFruit(bowl){
    this.strawberries = bowl.strawberries
    this.blueberries = bowl.blueberries
    
   if (bowl.strawberries == ""){
     this.strawberries = "there is none"
   }
 }

`this.strawberries = bowl.strawberries == "" ? "there is none" : bowl.strawberries;`??? You could do this in one line using the ternary operator. Or perhaps a default object? - [set-default-value-of-javascript-object-attributes](https://stackoverflow.com/questions/6600868/set-default-value-of-javascript-object-attributes) — Ryan Wilson, Sep 29 '22 at 20:07

Yes, you can write something like:

function CountOfFruit(bowl){
    this.strawberries = bowl.strawberries || "there is none";
    this.blueberries = bowl.blueberries || "there is none";
}

In that way, if one of the attributes is null or an empty string, the default value will be used.
