Hi Robin,

Thank you for this advice and I agree with you on the fact of having to do more
to support an example of this kind.

In fact, my example was a bit simplistic. However, with a more complex
selector, the QueryEventListeners would prove almost necessary for light
development.

Imagine, for example, that we want to apply an event to any element
corresponding
to:

document.querySelector('section:nth-of-type(3n+0) p[data-sample="sample"
a[href^="./"]]');

Should miles of code and it would be very expensive in ressources, to
manage it.

Also, my original example shows a user event (onclick) but it could very
well imagine that the event is simply inserting a node matching the selector
, so, for example, putting in color, supplement content, etc..

Michaël
