javascript - JS ForEach Loops in IE11

Question

I am having issues getting a JS loop to work over 4 elements on a page in IE11. I want the function hideImg to run on mouseover on the element that you hovered over.

Here is my code:

elements.forEach( function(element) {
    element.addEventListener('mouseover', hideImg);
});

I think I've found that forEach loops are not supported in IE, how can I easily convert this to a for loop in plain JS?

Kind regards,
Steve

You can do it like this:

var elements = document.getElementsByClassName("test");
for (var i = 0; i < elements.length; i++) {
  elements[i].addEventListener('mouseover', hideImg);
}

function hideImg() {
  console.log("hideImg called")
}

.test {
  width: 40px;
  height: 20px;
  border: green solid 1px;
}

<div class="test"></div>
<div class="test"></div>
<div class="test"></div>
<div class="test"></div>
