Stopping Event Propagation

You can stop an event from propagating further using stopPropagation(). This can be useful when you want an event to trigger only on a specific element without bubbling up to ancestors.

Example:

JavaScript

let innerDiv = document.querySelector("#innerDiv");
let outerDiv = document.querySelector("#outerDiv");

innerDiv.addEventListener("click", function(event) {
  alert("Inner div clicked!");
  event.stopPropagation();  // Stops the event here
});

outerDiv.addEventListener("click", function() {
  alert("Outer div clicked!");
});

Clicking innerDiv triggers only its alert because stopPropagation() prevents the event from bubbling up to outerDiv.
