` where the listener has been attached.
`event-delegation` will look from `event.target` (which is `
`) up to all parent elements until one matches the given `selector` (`a` in this case).
If none was found until the lookup process reaches the element on which event was originally attached to (`div` in this case) it stops and handler function is not triggered.
---
### Not matching example
```javascript
function divHandler(e) {
e.preventDefault();
}
document.querySelector('div').addDelegateListener('click', '.myclass', divHandler);
```
applied to the following HTML snippet:
```html
```
If a `click` event is triggered on `` the lookup process won't find any element matching with the given selector `.myclass`.
NOTICE that lookup will stops on `div` element, which is the one on which the listener is attached to, none of `div`'s parents will be considered and checked for matching.
**This improves performances and prevents any unwanted behaviour.**
