Most devs learn API calls. Very few understand how to protect them. Today's session hit differently we built real API use-cases and practiced error handling the way actual production apps do it. What we applied ↓ ⚡ async/await in real scenarios ⚡ try/catch with custom errors ⚡ Handling failed API requests ⚡ Simulating bulk tasks with Promise.all ⚡ Identifying which operation failed & why ⚡ finally() for cleanups This is the stuff that turns "JavaScript learners" into junior developers who can ship safely. Thanks to @sheryians_ & Harsh Sharma for making error handling actually make sense. JS feels less scary, more powerful. ⚡ #javascriptcommunity #100DaysOfCode #cohort2

Most people use Windows 11. Very few try to build it. 😭💻 I recreated a mini Windows 11 UI using HTML, CSS & JavaScript and learned WAY more than expected. Features I built: ✨ Start menu animation ✨ Right-click context panel ✨ Real-time date & time ✨ Smooth toggle behavior ✨ Dynamic positioning using event.clientX/Y ✨ Live updates with setInterval() Some JS I used 👇 querySelector() for UI elements addEventListener("click") for the Start menu contextmenu event to create a custom right-click panel new Date() padStart() for clean time formatting Every time the UI responded correctly, the dopamine was real. Frontend is basically engineering magic. 😭✨ @sheryians_ @harshbhaiyaa #javascriptcommunity #100DaysOfCode #cohort2

Most people see errors. Very few actually understand them. Today learned: → Syntax vs Runtime vs Logical errors → Error objects: name, message, stack → try–catch & try–catch–finally → How to throw custom errors → Handling errors in async code From fear ➝ clarity ➝ control. Now errors don't feel scary they feel debuggable. ⚡ After that, we even had a solid doubt-solving discussion session. That's where real learning locks in. @sheryians_ #javascriptcommunity #100DaysOfCode #cohort2
