Isnt it possible that after John Slegers:

Way 2 : adding properties after defining the function

Adding a Way 2.5

function doSomething() {
    doSomething.prop = "Bundy";
    doSomething.doSomethingElse = function() {
        alert("Why Hello There! ;)");

    };

    let num = 3;
    while(num > 0) {
        alert(num);
        num--;  
    }
}

sayHi();
sayHi.doSomethingElse();
alert(doSomething.prop);

var ref = doSomething;

ref();
ref.doSomethingElse();
alert(ref.prop);

Putting in both a "variable" property and a function property for completeness sake, straight in the function declaration. Thus avoiding it to be "disconnected". Left the inner default workings of the function (a simple loop) to show that it still works. No?
