DOM Attribute Methods: getAttribute, setAttribute, removeAttribute

Event Delegation lets you handle multiple events using a single parent listener. Instead of attaching listeners to each child element, you take advantage of event bubbling to manage everything efficiently. This approach is especially useful when working with dynamic content like todo lists, tables, or menus — where elements are added or removed frequently.

I broke my own rule today… and it paid off. I usually avoid adding new dependencies. But I needed faster validation for a complex form. Instead of reinventing everything, I used a lightweight validation helper. Saved time. Reduced bugs. Sometimes “don’t add libraries” becomes a limitation. The real rule should be: 👉 Add dependencies intentionally, not emotionally. Balance matters. Do you prefer building from scratch or using libraries? #webdev #javascript #productivity

😵 This one line in JavaScript can trick you! let a = 10; let b = a++; console.log("Addition", a + b, "a = ", a, "b = ", b) At first glance, you might expect both values to be the same… right? 🤔 But JavaScript has its own way of handling this. 👉 Why does b get 10 instead of 11? 👉 When exactly does the increment happen? 👉 And how is this different from ++a? This small concept can lead to big bugs if you misunderstand it. I’ve broken it down clearly in my latest video 🎥 Watch it once — you’ll never get confused again. #JavaScript #Frontend #WebDevelopment #Coding #LearnJavaScript

"I’m just going to say it: JavaScript Promises are hard. 🙃 I thought I had a handle on asynchronous code, but then came .then(), .catch(), and the logic of resolve vs reject. It’s one of those topics where you think you’ve got it, and then one unhandled rejection reminds you that you don't. Learning to code isn't always 'eureka' moments; sometimes it's just sitting with the frustration until it clicks. To my fellow devs—what was the one JS concept that finally made the lightbulb go off for you? #Javascript #WebDevelopment #CodingLife #LearnToCode"

5 React patterns that are silently killing your codebase. not bugs. not performance issues. just habits most devs never unlearn. in this carousel i break down: 🔴 useEffect for derived state — you don't need it 🟠 useMemo & useCallback everywhere — it's costing you more ⚡ re-renders — what actually triggers them (it's not what you think) 🟣 prop drilling 4 levels deep — there's a cleaner way 🔵 copy-pasting the same hook logic — extract it once swipe through ↓ (it's faster to learn this now than debug it at 5pm on a friday) which of these do you see most in codebases you've worked on? 👇 #react #javascript #webdev #frontend #softwareengineering

We often scare ourselves thinking writing custom code or polyfills is too complex. So we avoid it. Instead of overthinking the complexity, we can create a simple blueprint and move one step at a time. That’s exactly what I tried today. I picked something that usually feels intimidating . Built Redux from scratch . 🛠️ Not the real one - a tiny version with just three functions: getState, dispatch, and subscribe. That's it. That's Redux at its core. Just understanding: - how state is stored - how actions are dispatched - how listeners react to changes Sometimes, the best way to understand a tool is to rebuild it yourself. 👉 Checkout the repo for full code. https://lnkd.in/g_gHB_5S #javascript #redux #webdevelopment #frontend #learninginpublic #codingjourney

JavaScript Brain Teaser: The this Trap... Looks simple… but there’s a catch hiding in plain sight const obj = { name: "Deepak", first: function () { console.log("First:", this.name); }, second: () => { console.log("Second:", this.name); } }; obj.first(); obj.second(); Drop your answers in the comments Let’s see who truly understands what’s happening under the hood #JavaScript #CodingChallenge #Frontend #InterviewPrep #WebDevelopment

Short tips format: 5 React mistakes I see in every codebase: 1. useEffect for everything 2. No memoization strategy 3. Missing error boundaries 4. Props drilling 5 levels deep 5. No code splitting Save this for your next code review 🔖 #React #JavaScript #WebDev"

Demystifying Array Destructuring! 🌀 Ever wanted to simplify your code while handling arrays? Meet array destructuring! 🎉 This nifty feature allows you to unpack values from arrays into distinct variables in a clean and readable way. For instance, in a web project, you can easily extract user data from responses without the clutter. Let’s make your code elegant! 💪 Have you tried destructuring arrays before? Share your thoughts or experiences below! 👇 #WebDev #JavaScript #Coding #FrontendDevelopment #ArrayDestructuring

💡 useEffect Dependencies — Small Array, BIG Difference! One hook… three different behaviors — all based on the dependency array 🤯 Understanding this can save you from bugs and unnecessary re-renders! Let’s break it down 👇 🔹 1. No Dependency Array useEffect(() => { console.log("Runs on every render"); }); 👉 Runs after every render 👉 Can cause performance issues if not handled carefully 🔹 2. Empty Dependency Array [] useEffect(() => { console.log("Runs only once"); }, []); 👉 Runs only once (on mount) 👉 Perfect for: API calls Initial setup 🔹 3. With Dependencies [value] useEffect(() => { console.log("Runs when value changes"); }, [value]); 👉 Runs only when specific values change 👉 Best for syncing state, props, or side effects 🔁 Quick Summary No array → Every render [] → Only once [deps] → When dependencies change ⚠️ Common Mistake Forgetting dependencies can lead to: Stale data Unexpected bugs 👉 Always trust (and understand!) the dependency array. 🚀 Final Thought Mastering useEffect dependencies is the key to writing predictable and efficient React code. Once you get this right, everything starts making sense 🙌 #ReactJS #FrontendDevelopment #JavaScript #WebDevelopment #CodingTips
