I've been running into a couple of problems with javascript promises, particularly with stacked chains.   Can anyone explain to me the difference (if there is any!) between these different implementations?   IMPLEMENTATION 1  var serverSideProm...
I know it works, but I don't know why and how. What are the mechanics?  // Parent constructor function Parent(name){   this.name = name || "The name property is empty"; }  // Child constructor function Child(name){   this.name = name; }...
for example...  if ( /* Condition */ ) {      if ( /* Condition */ ) {          if ( /* Condition */ ) {            // Superb!          } else {            // Error 3          }      } else {        // Error 2      }  } else {    // Error 1  }   Do y...
This is a question for the guru of JavaScript. I'm trying to do work with JavaScript prototype model more elegant. Here is my utility code (it provides real chain of prototypes and correct work with instanceof operator):  function Class(conf) {...

I'm trying to use FileReader to read several files sequentially using promises for that. The problem is that I need to divide the reading operations in several chunks to make them doable. By doing so, I lose the Promise chain. This is what happen...

My code is :  function move(){  var A = new TWEEN.Tween(meshA.position).to({ z: -10 }, 2000).start();         var B = new TWEEN.Tween(meshB.rotation).to({ z: Math.PI }, 2000);        var C = new TWEEN.Tween(meshC.position).to({ x: 10 }, 2000);      A...
