JavaScript Functions & Events Explained | Build Interactive Web Apps (EP 04) Want to build interactive and dynamic websites using JavaScript? In this episode, we break down functions and events in JavaScript, two core concepts every developer must master. You’ll learn how to write reusable functions, understand function declarations vs arrow functions, and handle user interactions using event listeners. We also cover advanced performance techniques like debouncing, throttling, and event delegation to help you build faster and more efficient web applications. In this video, you will learn: ✔️ How JavaScript functions work ✔️ Function declarations vs function expressions vs arrow functions ✔️ How to use addEventListener properly ✔️ Understanding the event object ✔️ How to remove event listeners ✔️ Debounce and throttle explained simply ✔️ Event delegation for better performance If you want to improve your frontend development skills and write cleaner, more maintainable JavaScript code, this episode is for you.

We use a web browser every single day. But as a Front-End Developer, I asked myself — What actually is a web browser? And how does it work? A web browser is software that allows us to access websites. Examples? Chrome, Edge, Firefox. But here’s what really happens behind the scenes: 1️⃣ You type a URL 2️⃣ The browser sends an HTTP request to the server 3️⃣ The server responds with HTML, CSS, and JavaScript 4️⃣ The browser renders the content on your screen It also: • Parses HTML • Applies CSS styles • Executes JavaScript What feels instant is actually a powerful rendering engine working in milliseconds. Now when I build with React, I don’t just write UI — I understand how the browser interprets it. Fundamentals matter. — Priyanka C Frontend Developer in Progress #WebDevelopment #FrontendDeveloper #WebBrowser #JavaScript #HTML #CSS #ReactJS #SoftwareEngineering #TechLearning #LearningInPublic

I built and deployed a Calculator Web App using HTML, CSS, and JavaScript. Through this project, I practiced: • DOM manipulation • Event handling • Keyboard input handling • Writing calculation logic • Creating layouts with CSS Grid Each project is helping me get more comfortable with JavaScript and frontend development. I’m focusing on building consistently and improving step by step. 🌐 Live Project: https://lnkd.in/gzUeyfEx I’d really appreciate your feedback on the project. Also, what should I build next to improve my frontend skills? #WebDevelopment #JavaScript #Frontend #LearningInPublic #BCA

Sync notification count across browser tabs in JavaScript Problem: User opened two tabs. Marked notifications as read in one tab but the other tab still showed the unread badge. To sync across tabs, there are two approaches. 1. Using storage event: When one tab updates localStorage, other tabs receive an event. Pros: - Works almost everywhere - Very simple Cons: - Only works with string-based storage - Doesn’t fire in same tab 2. Using BroadcastChannel Pros: - Designed for cross-tab communication - Works for any message payload Cons: - Needs fallback for older browsers For modern apps, BroadcastChannel feels much cleaner. For maximum compatibility, storage event still does the job.

Day-21 : Throttling in JavaScript – Why Every Frontend Developer Should Know This When building modern web apps, performance matters. Imagine: A user scrolling fast Resizing the window Typing quickly in a search box If your function runs every single time the event fires, your app can become slow and unresponsive. That’s where Throttling comes in. 🔥 What is Throttling? Throttling ensures a function runs at most once in a specified time interval, no matter how many times the event is triggered. 👉 Example: If throttled to 1000ms, the function runs once per second, even if the event fires 100 times. 💻 Simple Throttle Implementation function throttle(func, delay) { let lastCall = 0; return function (...args) { const now = new Date().getTime(); if (now - lastCall >= delay) { lastCall = now; func(...args); } }; } 🎯 Real Use Cases ✅ Scroll event optimization ✅ Resize event handling ✅ Button click protection ✅ API call rate limiting ✅ Performance-heavy animations ⚡ Throttling vs Debouncing Throttling → Controls frequency (runs every X ms) Debouncing → Runs only after user stops triggering event Both are performance optimization tools — but used in different scenarios. #JavaScript #Throttling #FrontendDevelopment #WebPerformance #Webdevelopment #LearnaInPublic

Have you ever opened a webpage and noticed that the content appears instantly… but the buttons don’t work for a moment? Recently I was reading about 𝗥𝗲𝗮𝗰𝘁 𝗛𝘆𝗱𝗿𝗮𝘁𝗶𝗼𝗻, and it made me pause for a moment. When we build apps with React frameworks like 𝗡𝗲𝘅𝘁.𝗷𝘀, the page you see in the browser is often already rendered on the server. So when the page loads, the content appears very fast. You can read the text. You can see the buttons. But something interesting is happening at that moment. The page is actually 𝗷𝘂𝘀𝘁 𝗛𝗧𝗠𝗟. Buttons are visible, but the logic behind them isn’t active yet. Event handlers are not attached. State isn’t working. Then 𝗥𝗲𝗮𝗰𝘁 loads in the browser and starts connecting the JavaScript logic to that already rendered HTML. That process is called 𝗵𝘆𝗱𝗿𝗮𝘁𝗶𝗼𝗻. It’s basically the moment when a static page becomes a fully interactive React application. Understanding this small concept will help you to see why SSR makes pages feel faster, and also why sometimes we see 𝘩𝘺𝘥𝘳𝘢𝘵𝘪𝘰𝘯 𝘮𝘪𝘴𝘮𝘢𝘵𝘤𝘩 warnings.
