How to stop event bubbling in JavaScript

Ever faced this weird issue while building your project website? You add a few buttons — each meant to perform its own task — but when you click one, other buttons’ functions also get triggered. At first, it feels like a bug. But in reality, it’s because of something called event bubbling. Event bubbling happens when you have nested elements, like multiple <div>s each with their own onClick handler. When you click the innermost div, the event doesn’t just stop there — it “bubbles up” through its parent elements. So, if you have an inner → middle → outer div structure, clicking the inner div will trigger alerts for all three — inner, then middle, and finally outer. To stop this, we use: event.stopPropagation(); This ensures the event stays bound to that particular element and doesn’t bubble up to its parents. It’s one of those small JavaScript concepts that often causes big confusion during development — but once you understand it, you start writing cleaner and more predictable code. #javascript #webdevelopment #frontend #programming #developer #coding #learning #softwareengineering #webdev #tech
