Event Bubbling, Capturing and Propagation in JavaScript ? Frontend Interview Series 🔥 Episode 10

When working with events in JavaScript you have the option of using 'bubbling' or 'capturing' to define the order in which the event handlers fire off. In most cases, bubbling is default.
Typically you don't need to worry about capturing unless you need ultimate control over your event handlers. This concept is only relevant if you have a parent element and a child element which both have event listeners.
When using 'bubbling', events are fired off beginning with the child element and then go up to the parent.
In contrast, 'capturing' means that events are fired off from the parent first, and then down to the child element.
In this video I show you a simple example of how these two options differ along with Stop Propagation , Immediate Propagation & Prevent Default .

    Thanks, brother for the simple and effective explanations of Propagation in JavaScript. Lots of love! I have kept a note on both the concepts here for other devs out there. Note: Propagation in JavaScript: - In JavaScript, event propagation refers to the mechanism by which events are handled and propagated through the DOM hierarchy. There are two phases of event propagation: the capturing phase and the bubbling phase. Event Bubbling: - This occurs when an event is first captured by the innermost element and then propagates outward to its parent elements, all the way up to the document root. It starts from the target element and moves up the DOM hierarchy to the document root. This behaviour is similar to bubbles rising in water, hence the name "bubbling. Event Capturing: - This occurs when an event is first captured by the outermost element and then propagates inward to the target element. It starts from the document root and moves down the DOM hierarchy to the target element. This is often less intuitive than event bubbling but can be useful in certain situations. So, in summary: Event Bubbling goes from child to parent (inner to outer). Event Capturing goes from parent to child (outer to inner).
