🤔 What’s a Closure Anyway? Think of a closure as a special feature of function that remembers the environment it was created in. In other words, a closure can access variables from its own scope, the scope of the outer function, and even the global scope. It’s like having a super memory! 🧠Simple Terms,… Continue reading 🎯 Mastering JavaScript Closures: A In-Depth Guide

✨ Mastering JavaScript Event Delegation: An In-depth Guide!
What is Event Delegation? Event delegation is a technique that involves leveraging event bubbling to manage events at a higher level in the DOM rather than attaching event listeners to each element. This is particularly useful when you have many elements or when elements are dynamically added or removed. What is Event Bubbling? Before diving… Continue reading ✨ Mastering JavaScript Event Delegation: An In-depth Guide!
âš¡ Mastering JavaScript Web Workers: An In-depth Guide!
What Exactly Are Web Workers? Think of Web Workers as your secret agents who run in the background, handling tasks like complex calculations or data processing without slowing down your main thread. This means your web app stays smooth and snappy, even when you’re dealing with heavy tasks. Why Bother with Web Workers? JavaScript is… Continue reading âš¡ Mastering JavaScript Web Workers: An In-depth Guide!
How to Structure Your Backend Code in Node.js (Express.js)
When developing a Node.js application using Express.js, structuring your codebase effectively is crucial for maintainability, scalability, and ease of collaboration. A well-organized project structure allows you to manage complexity, making it easier to navigate and understand the code. In this blog, we’ll explore a typical folder structure for an Express.js application and explain the purpose… Continue reading How to Structure Your Backend Code in Node.js (Express.js)
JavaScript Event Loop: A Deep Dive
JavaScript, being a single-threaded language, executes one task at a time. However, it handles asynchronous operations with ease, thanks to the event loop. The event loop is a fundamental concept that powers JavaScript’s concurrency model, allowing it to manage multiple operations efficiently without blocking the main thread. In this article, we’ll explore the intricacies of… Continue reading JavaScript Event Loop: A Deep Dive
Threejs Scene creation
Creating the scene To actually be able to display anything with three.js, we need three things: scene, camera and renderer, so that we can render the scene with camera. main.js — import * as THREE from ‘three’; const scene = new THREE.Scene(); const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 ); const… Continue reading Threejs Scene creation
Threejs-Lines
Drawing lines Let’s say you want to draw a line or a circle, not a wireframe Mesh. First we need to set up the renderer, scene and camera (see the Creating a scene page). Here is the code that we will use: const renderer = new THREE.WebGLRenderer(); renderer.setSize( window.innerWidth, window.innerHeight ); document.body.appendChild( renderer.domElement ); const camera = new THREE.PerspectiveCamera(… Continue reading Threejs-Lines
Threejs-Creating text
Creating text There are often times when you might need to use text in your three.js application – here are a couple of ways that you can do so. 1. DOM + CSS Using HTML is generally the easiest and fastest manner to add text. This is the method used for descriptive overlays in most… Continue reading Threejs-Creating text
Threejs-Loading 3D Models
Loading 3D models 3D models are available in hundreds of file formats, each with different purposes, assorted features, and varying complexity. Although three.js provides many loaders, choosing the right format and workflow will save time and frustration later on. Some formats are difficult to work with, inefficient for realtime experiences, or simply not fully supported at… Continue reading Threejs-Loading 3D Models
Expanding Array of Objects Based on a Specified Quantity
In some scenarios, you might have an array of objects representing items in an order or list. Each item might have a quantity or count, and you need to expand this array so that each item appears multiple times based on its quantity. // Sample array of objects representing order line details let orderLineDetails =… Continue reading Expanding Array of Objects Based on a Specified Quantity
