Is it possible for me to declare attributes using a function object in a single statement?

Given an object obj, the following two-line statements can be defined:

 var obj ={} //this is an object
    obj.isShiny = function () {
        console.log(this);
        return "you bet1";
    };

These two lines can be combined into a one-line statement as shown below:

var obj={isShiny : function () {console.log(this);return "you bet1";}};

Similarly, for a function func with the following two-line statements:

 var func = function () {console.log(this)}; //this is a function
    func.isShiny = function () {
        console.log(this);
        return "you bet1";
    };

The question arises if it's possible to merge these statements into a single line?

Answer №1

Can it be condensed into a single line?

No, not in the way you're thinking.

You could technically put it all on one line, but it wouldn't be a single statement or expression.

You could have just one main statement or expression, though that probably isn't what you had in mind:

var func = (function() { function func() { console.log(this); } func.isShiny = function () { console.log(this); return "you bet1"; }; return func; })(); 

There's not much of a need for that, unless you were required to fill in a single expression slot (like as part of an object property initializer).

Answer №2

A great way to achieve this is by utilizing the Object.assign method:

var func = Object.assign(
    function() {console.log(this)},
    {
      isShiny: function () {
        console.log(this);
        return "you bet1";
      }
    }
);

Answer №3

Yet another response!

 if (typeof Function.prototype.method !== "function") {
            Function.prototype.method = function (name, implementation) {
                this[name] = implementation;
                return this;
            };
        }


        var myFunction =
                function () {console.log(this)}.method
                ("isGlowing",function () {
                    console.log(this);
                    return "absolutely radiant";
                });//this is a method


        console.log(myFunction.isGlowing());
