Is there any way for a variable to act as a reference to another variable? Could I have multiples variable all hold the same information regarding a single piece of data?  For example:  var foo = "data"; var bar = foo;  // I want this to set...
Javascript passes objects by reference. This makes perfect sense. But once you start manipulating those objects, everything acts in a way that seem unintuitive. Let me offer an example:  var a, b;  a = {} b = a; a['one'] = {};  console.log( J...
I have a generic question about javascript specification or implementation of functions pointer (delegates?) which are points to object methods.  Please, read the following code snippet. Here we have an object with a method using 'this' to ac...
Take a look at the following code:  var o;  (function (p) {     p = function () {         alert('test');     }; })(o);  o(); // Error: 'o is not a function'   In the above function I am creating an anonymous function that takes one pa...
In C, when there are variables (assume both as int) i less than j, we can use the equation    i^=j^=i^=j   to exchange the value of the two variables. For example, let int i = 3, j = 5; after computed i^=j^=i^=j, I have i = 5, j = 3.  However, if I u...
I have a javascript function that takes an object as a parameter.  I want one of the properties of passed object to be a function pointer.  But the function is executed which I don't want to happen.  Example:  var myFuncPtr = function(){alert(...

I have the following anonymous function:  (function() {  var a = 1;  var b = 2;   function f1() {  }   function f2() {  }   // this => window object!  // externalFunction(this); })();  function externalFunction(pointer) {  // pointer.f1(); => f...
