Making an object non-callable

Question

In JavaScript, functions are callable.

Can I remove this attribute from a function, leaving only a normal object?

var foo = function () {};
foo.[[ca         


        

Answer 1

this isn't an elegant solution, the idea is to create the "enabled" attribute as a flag to know if the function is enabled:

var foo = function () { 
  if(!arguments.callee.enabled){
    throw "function disabled";
  }
  console.log("Hello");
}

foo.enabled = true;
foo();
foo.enabled = false;
foo();
