Does IE 10 support event.target?

<ul id="navigation">
    <li><a href="Code libraries">Code libraries</a></li>
    <li><a href="Web sites">Web sites</a></li>
    <li><a href="Archives">Archives</a></li>
</ul>

<script>
window.onload = function () {
    var navigation = document.getElementById("navigation");
    navigation.onclick = function (evt) {
        var event = evt || window.event;
        var target = event.target || event.srcElement;
        var text = "Link's text: " + target.innerHTML;
        alert(text);
    }
};
</script>

Question:

If I changed :

var event = evt || window.event;
var target = event.target || event.srcElement;

to

var event = evt;
var target = event.target;

It still works in IE(I am using IE 10), Does this mean: IE10 also support event.target , and in the future I do not need to use this kind of code: var target = event.target || event.srcElement; var target = event.target || event.srcElement; ?

event.target is already available in IE9+. If you need to support IE6-8, then event.srcElement needs to be used.
