VS Code's Winning Features and Common Mistakes

JavaScript is single threaded, but handles async operations so smoothly 👇 That’s where the Event Loop comes in. At first, things seem simple: • Code runs line by line But then you see behavior like this: Even with 0ms, the timeout doesn’t run immediately. Because JavaScript uses: ✔ Call Stack ✔ Web APIs ✔ Callback Queue ✔ Event Loop Understanding this changed how I think about async code and debugging. Sometimes the delay isn’t about time, it’s about how the event loop schedules execution. #JavaScript #EventLoop #AsyncJavaScript #FrontendDevelopment #Programming

Most beginners use Promises because that's what tutorials show. But async/await exists for a reason — it's cleaner, easier to debug, and reads like normal code. Here's the side-by-side difference, with real code examples. Save this for when you hit your first API call.

#Day25 Today’s focus was on debugging. Not avoiding errors, but understanding them. Bugs can be frustrating, I know that but now I see them as clues. Things that helped today: => Read the error message carefully => Add logs at key points => Break the problem into smaller parts => Don’t rush — trace the flow I also noticed something: Most bugs aren’t “big problems”, they’re small assumptions that turned out to be wrong. A wrong path. An unexpected value. A step that didn’t run. Debugging forces you to slow down and actually see what your code is doing. #JavaScript #NodeJS #BackendDevelopment #Debugging #LearningToCode #M4ACELearningChallenge

TypeScript told you everything was fine. It lied. 8pm. Your phone buzzes. Slack from the CTO. "Something is broken in prod." You open the logs. undefined is not a function. But... the types were correct. You checked. TypeScript didn't complain. Then you see it. Someone used as SomeType three PRs ago to shut up the compiler. The API returned something different. TypeScript never saw it. It always is. TypeScript makes JavaScript safer. It doesn't make it safe. The gap is real. And it always shows up at the worst possible time. Rust makes a different promise. If it compiles, the type contract holds. Everywhere. Always. No casting your way out. No any as escape hatch. No "it should be fine" at 2am. That's a different guarantee entirely.

🔄 JavaScript Async Evolution Callbacks → Promises → Async/Await Here's what changed and why it matters: Callbacks — the OG way. Works, but nests into chaos fast. "Callback Hell" is real. Promises — cleaner chaining with .then() and .catch(). Big improvement, still a bit verbose. Async/Await — reads like normal code. try/catch for errors. Clean, simple, everyone loves it. ✅ Remember: Async/Await is just Promises under the hood. Learn both. Still working in a Callbacks codebase?

VS Code 1.115 is out and it's packed with improvements you'll actually use 🔧 Background terminals now notify agents automatically. SSH remotes set themselves up. File edits are tracked and restorable. There's a lot here. I broke down every update in plain English so you don't have to dig through the changelog yourself 👀 New post on hamidrazadev.com — link in bio! #vscode #webdev #javascript #programminglife #devtools #codenewbie #100daysofcode

🚀 LeetCode Challenge Update: 27/128 Just wrapped up “Container With Most Water” 💧 — a classic two-pointer problem that really tests how you think about optimization. At first glance, it feels like a brute-force problem… but the real magic is in reducing time complexity from O(n²) to O(n) using a smarter approach. 🔑 Key takeaway: Sometimes the best solution isn’t about checking everything — it’s about moving intelligently and eliminating unnecessary work. 📈 Progress: 27/128 Consistency > Motivation #LeetCode #128DaysOfCode #CodingJourney #DSA #JavaScript #ProblemSolving

Understanding JavaScript Execution Context changed how I debug code 👇 At first, JavaScript feels straightforward. But when things don’t behave as expected, execution context is usually where the answer lies. Every time a function runs, JavaScript creates a new execution context. Inside it: • Variables are created • Functions are stored • `this` is determined And all of this happens before the code actually executes. That’s why things like hoisting and scope behave the way they do. This behaves differently than many expect. Once I understood this, debugging became much clearer. Sometimes the problem isn’t the code, it’s understanding how JavaScript runs it. #JavaScript #ExecutionContext #FrontendDevelopment #SoftwareEngineering #Programming #LearningInPublic

Version 2.4.0.1 has been released with significant enhancements for those pairing IC with a JetBrains 2026.1+ free IDE, leveraging their newly-added first-class JavaScript, TypeScript, and CSS language support and adding full integration of LWC Jest test execution, debugging, and coverage analysis in those free IDEs.
