There may be thousands of libraries and utilities that allow you debug nodejs projects, but I am going to write few lines on how to do it using the node built-in tool. Is not nearly as powerful as gdb , but using the right strategy to approach the process can clarifying as well as timesaving, as you wont be needing to install some other addition...

Method chaining is a programming technique to allow better readiblity and writeability of objects, that allow you to call any instance method of the same object on the return object of another instance method. May be cryptic the definition, but lets see with an example. You declare a Class , with some instance methods (we are going to use pseu...

First of all there is not a clear definition of Standard-Library for Javascript as it depends on the context of execution that varies a lot , depending if you are running it on a Browser, or on a container such as node.js we will be using the later one. The global object is binded to globaThis So you can see all of the Global Objects derived fr...

Distinction between fields and properties Within a class body, there are a range of features available. The structure of a class definition via the class keyword is class MyClass { // Constructor constructor() { // Constructor body } // Instance field myField = "foo"; // Instance method my...

Runtime Code vs Library Code First of lets clarify a distinction between the following concepts in a programming language. Core or runtime code of a Programming language: Defines the interpreter or compiler Library Code : Code written on the same programming language (same level of abstraction) that defines basic functionalities that every...

Now that we have established the relationship between instanceObject.__proto__ (we are going to use Object.getPrototypeOf()) , and Constructor.prototype we see that. function Food () { } var popcorn = new Food(); console.log(Object.getPrototypeOf(popcorn) === Food.prototype); // True We can set its prototype properties as function Food () ...

In its most basic form proto is a built-in property in all objects in JS , that you set to other object so it inherits its properties. The firstObject will inherit secondObjects properties , and the properties of the secondObject.proto object and so on. let tangible = { isTouchable: true } let resource = { hasUtility: true, __proto_...

First off All object literals in javascript inherit from Object.prototype global object var myObject = { }; console.log(myObject instanceof Object); // True console.log(myObject instanceof Function); // False Also, out of the inheritance model we can say that Javascript objects have a property called prototype accessed as proto ,...
