JavaScript Design patterns - The Constructor Pattern Introduction In this article, I would like to explain how to use Object.defineProperty() and Object.defineProperties() methods. These two methods define new or modify existing properties directly on an object, returning the object (Visit MDN, whi...
In this example, we define a classdelftstackwith a constructor method that accepts variable arguments*args. Inside the constructor, we check the type of the first argument passed (args[0]). If it’s an integer, we assign it directly to theansattribute of the object. If it’s a string,...
Since design patterns are used to solve specific problems in software, let’s try to define such a problem and work to solve it using a design pattern in JavaScript. With the rise of frameworks likeReact, we often hear about ‘application/component state.’ When the state is updated, compon...

In this code, we define aUserstruct with three fields:firstName,lastName, andemail. We create anewUserfunction, acting as a constructor, which takes parameters for each field and returns a pointer to a newly initializedUserstruct. In themainfunction, we use this constructor to create a new...
