JavaScript Async/Await & Promises Explained with Examples

JavaScript Promise & Async/Await Blog Understanding JavaScript Promises & Async/Await In this blog, we will learn how to handle asynchronous tasks in JavaScript. JavaScript is single-threaded, so long-running tasks like network requests can block the program. That’s why we use Promise, async/await, and try/catch/finally to manage them efficiently. 1. What is a Promise? A Promise is an object that represents the future result of an asynchronous task . const myPromise = new Promise((resolve, reject) => { const success = true; if (success) { resolve("✅ Success!"); } else { reject("❌ Failed!"); } }); myPromise .then(msg => console.log(msg)) .catch(err => console.log(err)); .then() → handles success, .catch() → handles errors. ...

Image
🧠 What I Learned Switching from Vue to React (…but still a Vue Dev) As a frontend developer primarily working with Vue.js , I recently took some time to explore React . It was a challenging yet eye-opening experience — and while I still prefer Vue for most projects, here's what I learned along the way: What I Learned Switching from Vue to React – Visual Framework Comparison ⚛️ JSX is powerful, but takes time React uses JSX — a syntax extension that lets you write HTML-like code inside JavaScript. While it's incredibly powerful and flexible, it can feel messy compared to Vue’s clean <template> structure. Once you get past the learning curve, it starts to make sense — especially for building highly dynamic UIs. 🔄 Hooks are a big brain shift React's hook system ( useState , useEffect , etc.) is powerful but takes time to master.
