💡 What is Ternary Operator in React? The ternary operator is used for conditional rendering in React. 👉 Syntax: condition ? trueValue : falseValue 📌 Example Use Cases: • Show / hide elements • Login / Logout button • Loading states • Toggle UI 📌 Why use it? • Cleaner than if-else • Inline rendering • Easy to read ⚡ Helps you write dynamic UI logic directly in JSX.

🚀 Day 5 of my JavaScript Coding Practice Today’s challenge was all about understanding closures 🔥 Problem: Create a counter function that starts from a given number n and increments by 1 every time it’s called. var createCounter = function(n) {    let increment = 0;   return function () {     let retCount = n + increment;     increment++;     return retCount;   }; }; #JavaScript #Closures #DSA #CodingPractice #100DaysOfCode #FrontendDevelopment

Problem: JavaScript’s `.sort()` mutates the array. Solution: Use `.toSorted()` instead. It returns a new sorted array. —— 👋 Join 30,000+ SWEs learning JS, React, Node.js, and Software Architecture: https://thetshaped.dev/ ——— 💾 Save this for later. ♻ Repost to help others find it. ➕ Follow Petar Ivanov + turn on notifications. #javascript #softwareengineering #programming

🔥 Still managing async code with nested callbacks and manual timeouts? There's a better way. I put together a visual breakdown of RxJS — what pain it solves, how it works, and why it's a game-changer for JavaScript developers. Here's what's inside 👇 ✅ The async nightmares RxJS eliminates ✅ Before vs After — real code, real difference ✅ 8 essential operators every dev should know ✅ Real-world use cases from search to WebSockets If you're building anything with events, HTTP calls, or real-time data — this one's for you. Drop a 🔁 if you've ever been lost in callback hell. #RxJS #JavaScript #WebDevelopment #Angular #FrontendDevelopment #ReactiveProgramming #Programming #100DaysOfCode

JavaScript Closures Explained Complete Notes for Developers Closures are one of the most powerful and important concepts in JavaScript. They allow a function to access variables from its outer scope even after the outer function has finished executing. Understanding closures helps you master data privacy, function factories, callbacks, and advanced patterns used in modern frameworks like React. These notes break down closures in a simple and practical way with clear explanations and real-world use cases to strengthen your core JavaScript knowledge. If closures confuse you, your JavaScript fundamentals are weak. #JavaScript #Closures #JSConcepts #WebDevelopment #FrontendDevelopment #LearnJavaScript #Programming #DeveloperNotes #Coding #SoftwareEngineering

Instead of creating separate state for every input… You can manage all inputs using one state object. 👉 Use one state → store all form fields 👉 Use name attribute → identify input 👉 Update dynamically using onChange 📌 Example fields: • name • email • password 📌 How it works: 1️⃣ Create one state object 2️⃣ Add name to inputs 3️⃣ Use one onChange handler 4️⃣ Update using [name]: value ⚡ This makes your form: ✔ Cleaner ✔ Scalable ✔ Easy to manage Master this to build real-world forms in React.

30 Days JavaScript Challenge: Day 18 ✅ Today’s problem was about implementing a debounce function. The idea is simple but very useful delay the execution of a function, and if it gets called again within that delay, cancel the previous call and restart the timer. This concept is widely used in real-world scenarios like: • search input optimization • reducing unnecessary API calls • handling rapid user events It was a great exercise to understand how timers and function control work together in JavaScript. 18 days in getting more comfortable with concepts that are actually used in real applications. 💻🚀 #javascript #leetcode #webdevelopment #frontenddeveloper #codingchallenge #learninginpublic #developers #programming #buildinpublic
