Debugging is an essential skill for every JavaScript developer. It helps identify and fix errors, optimise performance, and improve the overall quality of code. While basic debugging techniques like console logging are widely used, advanced techniques can greatly enhance your debugging capabilities. In this article, we will explore some advanced debugging techniques and learn how they can be effectively used to debug JavaScript applications. Using Breakpoints Breakpoints allow us to pause the execution of our code at a specific line and inspect the program's state. Modern browsers provide powerful debugging tools that enable setting breakpoints directly in the code or ... Read More
Django, a popular web framework written in Python, follows the Model−View−Template (MVT) architectural pattern. MVT is a variation of the well−known Model−View−Controller (MVC) pattern and provides a structured approach to building web applications. Understanding how to create a basic project using MVT in Django is a fundamental step toward developing robust and scalable web applications. In this article, we will delve into the process of creating a basic project using MVT in Django. We will walk you through the essential steps, from setting up the project to defining models, views, templates, and URL patterns. By following this tutorial, you will ... Read More
Python offers various methods to manipulate lists, which are one of the most commonly used data structures. One common task when working with lists is to count the occurrences of unique values within them, which is often required in data analysis, processing, and filtering tasks. In this article, we will explore four different approaches to counting unique values inside a list in Python. In this article, we will cover using a set, a dictionary, list comprehension, and a Counter from the collections module. Each method has its own advantages and can be chosen based on the specific requirements of ... Read More
In today's rapidly evolving web development landscape, JavaScript has emerged as the backbone for building interactive and dynamic web applications. As JavaScript applications grow in complexity, developers face the challenge of managing and optimising their code effectively. This is where advanced JavaScript tooling comes into play. In this article, we will explore three indispensable tools for modern JavaScript development: Webpack, Babel, and ESLint. These tools work seamlessly together to enhance code quality, optimise performance, and enable the use of cutting-edge JavaScript features across different environments. Webpack: Bundling Your Code Webpack serves as a powerful module bundler that allows developers to ... Read More
JavaScript is a versatile programming language that allows developers to create dynamic and interactive web applications. With its vast array of features and flexibility, JavaScript enables the implementation of various design patterns to solve complex problems efficiently. In this article, we will explore three advanced JavaScript patterns: Singleton, Decorator, and Proxy. These patterns provide elegant solutions for managing object creation, adding functionality dynamically, and controlling access to objects. Singleton Pattern The Singleton pattern ensures that a class has only one instance and provides a global point of access to it. This pattern is useful when we want to limit the ... Read More
As web development continues to evolve, creating engaging and interactive user experiences has become an essential part of modern web applications.

Functional Reactive Programming (FRP) is a powerful paradigm that combines functional programming concepts with reactive programming. By leveraging FRP, developers can build highly responsive and scalable applications by modeling the flow of data and events as streams of values. JavaScript, being a widely used language for web development, can benefit from FRP through libraries and frameworks. One popular library is RxJS (Reactive Extensions for JavaScript), which provides a rich set of tools for implementing FRP in JavaScript. In this article, we will explore advanced techniques of Functional Reactive Programming using JavaScript and RxJS. Understanding FRP and Reactive Programming Before diving ... Read More
What is Spatial Computing? Spatial computing is a technological field that combines components of physical world and computer science to create a user interface which is more immersive and interactive. Spatial computing involves the tools and processes to record and process the three-dimensional data. The major elements of spatial computing include the advanced technology tools like virtual reality (VR), augmented reality (AR), mixed reality (MR), IoT, artificial intelligence (AI), physical controls, etc. All these components combine the digital systems and physical world together. Fundamentally, spatial computing uses technology that understand and interact with the world in spatial terms. Spatial computing ... Read More
What is the Blue Screen of Death? Blue Screen of Death (BSOD) is an error screen which displayed due to driver error or hardware failure in a Windows OS based computer system. It is called BSOD because it is one of the critical system errors at the Windows Kernel level. Hence, the system cannot be recovered from it. The following picture depicts a Blue Screen of Death (BSOD) with a stop error code “CRITICAL_PROCESS_DIED”. Whenever the Blue Screen of Death error occurs, the system stops working and a blue screen is displayed with an error message. The error message ... Read More
