I wanted to understand as to how do we zoom an image using a zoom bar with buttons for zoom in and zoom out

What I have tried:

.img-zoom {
height : 80%;
overflow : auto;
text-align:center;
font-weight: 70%;
overflow : auto;
}
.img-zoom img {
vertical-align : middle;
margin : 0;
padding : 0;
border : 0;
transition : transform 0.5s ease;
zoom: 1.2;
}
<pre>const zoomElement = document.querySelector(".img-zoom");
let zoom = 1;
const ZOOM_SPEED = 0.1;

document.addEventListener("wheel", function (e) {
  if (e.deltaY > 0) {
    zoomElement.style.transform = `scale(${(zoom += ZOOM_SPEED)})`;
  } else {
    zoomElement.style.transform = `scale(${(zoom -= ZOOM_SPEED)})`;
  }
});

There is a small change in the code:
var imagesize = $('img').width();

$('.zoomout').on('click', function(){
imagesize = imagesize - 30;
$('img').width(imagesize);
});

$('.zoomin').on('click', function(){
imagesize = imagesize + 30;
$('img').width(imagesize);
});
