React useRef vs querySelector: DOM manipulation in React

Day 72 / 365 👨💻 Continued learning React today. 🧠 Understood what React actually is 🔗 Learned what ReactDOM does ⚖️ Compared React vs ReactDOM 🧱 Looked at why they’re separate (native, PDF, etc.) ⚙️ Tried building a simple custom ReactDOM renderer 🚀 Learned about React 18 createRoot rendering ✨ Saw why JSX becomes useful #365DaysOfCode #React #JavaScript #Frontend

✨ Master JavaScript Array Destructuring for Cleaner Code Modern JavaScript lets you extract values in one line—making your code shorter, clearer, and easier to maintain. 🧠 Why it matters: Readable code = fewer bugs + faster development. ⚛️ If you’re using React, you’re already using destructuring (useState, useReducer). #JavaScript #FrontendDevelopment #WebDevelopment #ReactJS #CleanCode #ModernJS #SoftwareEngineering

💡3 Common Mistakes Beginners Make in React 1️⃣ Not understanding useEffect dependencies 2️⃣ Mutating state directly instead of using useState setter 3️⃣ Not breaking UI into reusable components Avoiding these can save a lot of debugging time 👆 I’m currently improving my React skills daily 🚀 #reactjs #javascript #webdevelopment #learninginpublic #frontenddeveloper

JavaScript is single-threaded. So how does it run setTimeout, Promises, and await without blocking everything? The answer is the event loop. But most explanations make it sound more complicated than it actually is. Async in JavaScript isn’t magic. It’s just a predictable system of queues: • Call Stack • Microtask Queue • Macrotask Queue • Rendering cycle Once you understand how these queues run, the execution order suddenly makes sense. No more “Why did this run first?” moments. I broke the whole concept down visually in this carousel. If async has ever confused you while debugging Save this post, you’ll want it later.

While learning JavaScript, I wanted to understand the actual flow of asynchronous operations. This simple diagram shows the sequence from fetch() to Promises, async/await, error handling with try/catch, and finally organizing code using ES Modules. I learned these concepts from Devendra Dhote bhaiya and tried to visualize the flow in a simple way. Breaking concepts into small visual steps makes asynchronous JavaScript much easier to understand. #javascript #webdevelopment #frontend #learninginpublic #sheryians

🚀 Day 947 of #1000DaysOfCode ✨ The Shortest JavaScript Program (You’ll Be Surprised 😮) This is one of those concepts that looks super simple… but completely changes how you see JavaScript. In today’s post, I’ve broken down the shortest possible JavaScript program — and trust me, it’s not just about writing less code. Behind this tiny piece of code lies how JavaScript actually runs your program, creates execution context, and prepares memory before even executing a single line. Sounds crazy? Wait till you see it. This is the kind of concept that once you understand, a lot of “weird JavaScript behavior” suddenly starts making sense. If you’re serious about mastering JavaScript, you don’t want to miss this one. 👉 Swipe through the carousel — this might blow your mind 🤯 👇 Did you already know what the shortest JS program is? #Day947 #learningoftheday #1000daysofcodingchallenge #FrontendDevelopment #WebDevelopment #JavaScript #React #Next #CodingCommunity #JSDeepDive

Day 8 of #100DaysOfCode Built a Stopwatch using JavaScript. Features: ⏱️ Start / Stop functionality. 🔄 Reset timer 📊 Real-time time tracking Continuing to improve my JavaScript fundamentals through small projects. Git-Hub Repo Link: https://lnkd.in/geZqCnQ9 #JavaScript #WebDevelopment #Frontend

JavaScript is fast and flexible. TypeScript catches errors before they happen. Small projects? JS is perfect. Big projects? TS is a lifesaver. Which one do you reach for first? #JavaScript #TypeScript #WebDevelopment #CodingLife

Learning frontend isn’t about memorizing everything… it’s about understanding how things work together. You don’t need to know every React hook. You need to know when and why to use them. Still figuring things out, but that mindset shift changed a lot for me. #Frontend #JavaScript #LearningToCode
