Understanding JavaScript Hoisting in Programming

Your browser is not the only place you can see your JavaScript log. You can see it on vs code terminal, here is how? #javascript #react #codingtips #programming

Stack vs Heap in JavaScript Primitives (number, string, boolean, etc.) are stored in the stack — copied by value. Objects, arrays, and functions are stored in the heap — copied by reference. Change a primitive → only that variable changes. Change an object → every reference sees the update. Understanding this prevents subtle bugs and improves your JS fundamentals. #JavaScript #WebDevelopment #FullStack #Programming

Practiced the difference between normal functions and arrow functions in JavaScript. => In a normal function, this refers to the object calling it => In an arrow function, this does not bind to the object Understanding this behavior helps avoid many silent bugs in JavaScript. #JavaScript #JavaScriptBasics #ArrowFunctions #ThisKeyword #WebDevelopment #FrontendDevelopment #LearningInPublic #CodingJourney #100DaysOfCode #BuildInPublic #DeveloperLife #Programming

Day 6 of “Js in bits series – (Datatypes - Boolean)” Here are a few key ideas covered in the article: 🔹 What null represents in JavaScript 🔹 The difference between null and undefined 🔹 Why typeof null returns "object" (one of JavaScript’s historical quirks) 🔹 Practical examples of when to intentionally use null 👉 https://lnkd.in/gTA8tarr #javascript #webdevelopment #frontend #programming #softwareengineering #learning

🚀 JavaScript Concept – What’s the Output? An object is stored inside an array and then the original variable is set to null. Does this change the value inside the array? 🤔 This question tests your understanding of references in JavaScript.

Many beginners in JavaScript get confused between null and undefined, but the difference is actually simple. When a variable is declared but not assigned any value, JavaScript automatically gives it the value undefined. This means the variable exists, but it hasn't been initialized yet. On the other hand, null is a value that is intentionally assigned by the developer to indicate that the variable should contain no value. In simple terms: undefined → variable exists but no value has been assigned yet. null → developer deliberately sets the variable as empty. Pro Tip: Use null when you intentionally want a variable to be empty. If you just declare a variable without assigning anything, it will automatically be undefined. #JavaScript #WebDevelopment #FrontendDevelopment #CodingTips #LearnToCode #Programming #SoftwareDevelopment #Developers #TechLearning #CodingCommunity #100DaysOfCode #JavaScriptTips #CodeNewbie #WebDev

🚀 React Series: Day 9 – Mastering the useRef Hook useRef is essential for direct DOM access and storing mutable values without triggering unnecessary re-renders. 💡 It optimizes performance by maintaining persistent data across the component's lifecycle efficiently. #ReactJS #WebDevelopment #FrontendDeveloper #JavaScript #CodingTips #SoftwareEngineering #ReactHooks #Programming #WebDesign #Techcommunity #UIUX #FullStackDeveloper

Every property access walks the prototype chain — and that single mechanism explains: • how methods are shared • Why memory usage stays low • how classes and frameworks actually work If you understand this, JavaScript stops feeling “magical” and starts feeling predictable. #JavaScript #WebDevelopment #SoftwareEngineering #Frontend #InterviewPrep #Programming
