I am aware of how to create getters and setters for properties whose names one already knows, by doing something like this:  // A trivial example: function MyObject(val){     this.count = 0;     this.value = val; } MyObject.prototype = {     get va...

Is it possible, given an object and property name to determine if that property is defined using either a getter or setter, or is it completely transparent? I only want to define a getter/setter if there is not already one defined on the property.  I...

ECMAScript allows us to define getters or setters as following:  [text/javascript]  var object = {   property: 7,   get getable() { return this.property + 1; },   set setable(x) { this.property = x / 2; } };   I can work around if I'm using a cla...

I would like to extend localStorage by executing some code each time a setting is fetched/stored. I could define a getter/setter for all existing properties of localStorage, but the problem lies in new settings.  For example, localStorage['somene...

I am trying to solve a problem that came to my mind lately.  Let's say we would want and would know how to make a point in having dynamic getters and setters in javascript, more like those in php (__get, __set). But as javascript does not have a...

Consider the following code:  var x = 0;  var o = {};  function getter() {     return x; }  Object.defineProperty(o, "y", {     get: getter,     set: function (y) {         x = y;          Object.defineProperty(o, "y", {             g...

I have an object that contains a getter.  myObject {     id: "MyId",     get title () { return myRepository.title; } }  myRepository.title = "MyTitle";   I want to obtain an object like:  myResult = {     id: "MyId",      titl...

Is there any point in repeating this pattern for every property in JavaScript?  class Thing {   get myProp() {     return this._myProp;   }   set myProp(value) {     this._myProp = value;   } }   I understand that getters/setters can be useful if you...

Asking about Object.defineProperty as demonstrated below:  function testComponent(){     var testProperty;     Object.defineProperty(this, "testProperty",     {         get : function()         {            return testProperty;         },...

class AbstractClass {      constructor() {     }      set property(value) {         this.property_ = value;     }      get property() {         return this.property_;     }  }  class Subclass extends AbstractClass {      constructor() {         super...
