Mastering concurrency with JavaScript/Node.JS

Concurrency is the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order…

Mastering concurrency with JavaScript/Node.JS JavaScript introduced Promises and async functions to execute code without blocking the thread during I/O like network calls or reading files etc using event loop instead of waiting till the operation is complete…

7 JavaScript Design Patterns Every Developer Should Know

A template for every project? Sounds amazing, isn’t it? That’s also a level of coding I’m striving for. One of the ways to achieve it is using design patterns, which help to write well-structured, beautiful, and organized codes. In this story, we will discover some of the common design patterns used in JavaScript. Let’s get into it.

Deep Dive Into Design Patterns With JavaScript. The Builder Pattern

The builder design pattern allows for the creation of a complex object in a procedural manner. Imagine a scenario where you’re creating an application that allows the user to build their own house. Since you want your users to like your product, you provide them a tremendous amount of options. They can add pools, gardens, internet, walls, and even a roof (imagine that, a real roof!). There are several ways to approach this from a code perspective.

Design Patterns: Singleton Pattern in Modern C++

In software engineering, Creational Design Patterns deal with object creation mechanisms, i.e. try to create objects in a manner suitable to the situation. The basic or ordinary form of object creation could result in design problems or added complexity to the design. In this article of the Creational Design Patterns, we’re going to take a look at the much-hated & commonly asked design pattern in a programming interview. That is Singleton Design Pattern in Modern C++ which criticizes for its extensibility & testability. I will also cover the Multiton Design Pattern which quite contrary to Singleton.

JavaScript Design Patterns - Observer Pattern

JavaScript Design Patterns - Observer Pattern. The Observer pattern is a design pattern that offers a subscription model in which objects (known as 'observers') can subscribe to an event (known as a 'subject') and get notified when the event occurs (or when the subject sends a signal). This pattern is the cornerstone of event driven programming.

JavaScript Design Patterns - Iterator Pattern

JavaScript Design Patterns - Iterator Pattern. The Iterator pattern is a pattern that allows you to effectively loop over a collection of objects. A common programming task is to traverse and manipulate a collection of objects. These collections may be stored as an array or perhaps something more complex, such as a tree or graph structure. In addition, you may need to access the items in the collection in a certain order, such as, front to back, back to front, depth first (as in tree searches), skip evenly numbered objects, etc.
