Is the "slot" a fallback word in the new version of ECMAScript?

This is a problem with google chrome version 53.0.2785.101 (64-bit). I tried to run a simple html file and it gives the error “slot.testFun is not a function” when I used the word “slot”.

<html>
<head>
    <title>TEST</title>
</head>
<body>
    <a href="#" onclick="slot.testFun();">Click Here</a>

    <script type="text/javascript">
        var slot = {
            testFun: function(){
                console.log('clicked');
            }
        }
    </script>
</body>
</html>

There are no conflicts with this variable in our code. It is simply a browser that does not allow the variable name in this latest version.

If you use any name other than the word "slot", it works fine.

This is not an ECMAScript problem, this is a DOM problem.

slot, onclick with, this.slot.testFun(), slot ( ), .

slot DOM, slot Chrome 53. Chrome 52 , , .

: . DOM. DOM.

<a href="#">Click Here</a>

<script type="text/javascript">
    var slot = {
        testFun: function(){
            console.log('clicked');
        }
    }
    document.querySelector("a").addEventListener("click", slot.testFun);
</script>
