Object.create() in JavaScript Explained with Practical Examples

Image
If you’ve been learning JavaScript objects, you’ve probably come across Object.create() . Most tutorials briefly mention it with a small example and move on quickly. However, in real-world applications, Object.create() is much more powerful than it looks. It allows developers to create objects directly from other objects, control property behavior, and design flexible inheritance systems without relying on constructors. If you want a deeper understanding of JavaScript objects in general, I recommend reading my complete guide first: JavaScript Objects Deep Dive By the end of this guide, you will know when Object.create() is the right choice and how it helps you build cleaner and more efficient JavaScript code. What is Object.create() in JavaScript? In JavaScript, Object.create() is a built-in method used to create a new object using another object as its prototype. Instead of copying properties from the original object, JavaScript links the new object to the pr...

Understanding the JavaScript Prototype Chain (Complete Guide with Examples)

Image
JavaScript objects are the foundation of almost everything you build in JavaScript. But what makes objects truly powerful is something called the prototype chain . The prototype chain allows JavaScript objects to inherit properties and methods from other objects without copying them, making inheritance efficient and memory-friendly. If you want to understand how objects themselves work in detail — including property descriptors, getters, setters, and ES6 classes — you can also read our complete guide on JavaScript Objects Explained (Deep Dive) . In this article, we will focus specifically on the prototype chain and understand how JavaScript searches for properties behind the scenes. In this complete guide, you will learn: What the JavaScript prototype chain is How property lookup works internally What __proto__ actually does How Object.getPrototypeOf() works What property shadowing means How to debug prototype chains in DevTools Common mistakes developers make Freq...

How to Plan Projects Before Coding | Developer Guide (2026)

Image
Starting a new software project feels exciting. But if you skip planning and jump straight into coding, you’ll likely waste days fixing bugs and rewriting features later. This beginner-friendly guide explains how to plan projects before coding , improve your software development workflow , and use simple system design basics to avoid common mistakes. Because honestly… I learned this the hard way. This guide is exactly what I wish someone had taught me about project planning for developers when I started coding. Why Planning Projects Before Coding Matters Every time I got a new project idea, I used to do the same thing. Open VS Code. Create a new folder. Install dependencies. Start coding immediately. No thinking. No planning. Just pure excitement. At that moment, it felt productive. Typing fast. Creating components. Writing APIs. Seeing the UI come alive. I thought, "This is how real developers work — just build fast." But a few days later? Eve...

Building a Backend from Scratch at Work — Bugs, TypeScript Struggles, and Finally a Green CI Build

Image
If you're building a backend from scratch at work, especially using TypeScript and CI tools like GitHub Actions, you're going to face more than just writing APIs. When we build personal projects, backend development feels pretty simple. Create a few APIs, connect the database, test locally… done. But real-world development at work? It hits very differently 😅 Recently, I was assigned a task that sounded small at first: “There are no APIs for this feature. Please build the backend.” That one sentence meant something big — no existing routes, no controllers, no services… nothing. Everything had to be designed and developed from scratch. At first, I felt excited. Building a backend myself sounded fun. But within a few hours, that excitement slowly turned into debugging, TypeScript errors, database issues, security warnings, and GitHub Actions failures. It was messy. Frustrating. Challenging. But honestly? It became one of the best learning experienc...

Understanding Promises, Async & Await in JavaScript (Without Callback Hell)

Image
If you’ve ever worked with JavaScript long enough, you’ve probably faced this moment… Your code starts simple. One API call. Easy. Then you add another. Then another. Suddenly your file looks like a staircase going sideways. Brackets everywhere. Indentation chaos. Debugging feels impossible. Before we dive deeper, having a strong foundation in core JavaScript concepts really helps. If you’re still exploring the basics, you might like our guides on JavaScript’s this keyword and JavaScript objects deep dive . Welcome to Callback Hell. In this guide, we’ll walk step-by-step through the journey from callbacks → promises → async/await using simple language, real examples, and visual diagrams so you can finally feel confident writing asynchronous JavaScript like a pro. 🌪 The Real Problem: Callback Hell Let’s start with a small story. Imagine you’re building an app that: Fetches a user Gets their orders Add to cart Applying discount Processes payme...

Why Your Child Component Isn't Updating Parent State in React (And How to Fix It)

Image
If your child component isn't updating parent state in React , you're probably running into React's one-way data flow. Let me tell you a quick story. One day, I was building a small React feature. Nothing fancy — just a parent page and a child component. Props were passing correctly. The UI looked clean. No console errors. Everything seemed perfect… Until I clicked a button inside the child component. And nothing happened. The parent didn't update. The UI didn't change. React just stared back at me like: "Not my problem bro." 😄 If you've ever searched: React props not updating child component not updating parent state how to send data from child to parent in React React state not syncing between components Don't worry — you're not doing anything wrong. This is simply how React's one-way data flow works. The Situation Most React Developers Face Parent shows a username. Child has an input. When you typ...

How to Analyze YouTube Comments with Python (Sentiment Analysis Guide)

Image
Last month, I uploaded a tutorial video that I had worked on for days. I expected a few comments… maybe ten or twenty. Instead, the next morning I woke up to 300+ comments . Some people said “Great explanation!”. Some said “Too fast, couldn’t follow.” A few even complained about the audio quality. At first, I tried reading every single comment manually. After 15 minutes, I gave up. Scrolling endlessly through feedback is exhausting. And honestly, it’s hard to see the bigger picture that way. That’s when I thought: “Can’t Python just read these comments for me and tell me how people feel?” Turns out… it absolutely can. In this guide, you’ll learn how to perform YouTube comment sentiment analysis with Python — step by step — so you can automatically understand whether your audience is happy, frustrated, or neutral about your videos. What Are We Building Exactly? The goal is simple. We want a small Python script that can: Download comments from ...
