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(...

Very sure this is a duplicate but I don't really know what to search for. So please bear with me...  In the example below it looks like childRef points to the original object assigned to someParentObj.someChildObj and therefore when someParentObj...
I have been using a function pointer, p, to call different functions. My problem is, the performance of calling p decreases dramatically if I point it to a different function after it has already been assigned a function. The performance is fine if I...
Given the following code:  let obj = { data: 1 }; let ref1 = { data: obj }; let ref 2 = [ obj ];   How can I delete obj is such a way that it's references are also removed? (I mean that ref1.data === null && ref2.length === 0)  Is it poss...
