I'm using a found code where event is used. It works, but I would like to know what should be used instead.
I'm a novice programmer and there are a concepts that I'm missing. in this case, I'm using a code I found in the web, that can be found in the next link:

PhpStorm shows me that event on onmousemove=zoom(event) is deprecated. I have tried erasing it but it does not work that way. I would like to know what should I use instead of event.
<figure class=zoom onmousemove=zoom(event) style=background-image: url(//res.cloudinary.com/active-bridge/image/upload/slide1.jpg)>
<img src=//res.cloudinary.com/active-bridge/image/upload/slide1.jpg />
</figure>
function zoom(e){
var zoomer = e.currentTarget;
e.offsetX ? offsetX = e.offsetX : offsetX = e.touches[0].pageX
e.offsetY ? offsetY = e.offsetY : offsetX = e.touches[0].pageX
x = offsetX/zoomer.offsetWidth*100
y = offsetY/zoomer.offsetHeight*100
zoomer.style.backgroundPosition = x + '% ' + y + '%';
}
