vseventer / callable-object.js
Last active July 10, 2016 10:31
Create a callable object in JavaScript which returns an isolated clone of itself. This is *not* a class, hence using the new keyword has no effect.
// How to define:
// --------------
var callableObjectFn = function() {
// Use CallableObject as name in constructor function, but also when setting property below.
var CallableObject = (function(CallableObject) {
return function() {
return CallableObject();
};
}(callableObjectFn));
CallableObject.property = 'value';
