Why this does not work.

<!DOCTYPE html>

</style>
</head>
<body><div style="height:200px;width:200px;background:red;"><button>JJJJJ</div>
 <script>
 const div = document.querySelector('div')
div.addEventListener('click',function(e){
if(e.currentTarget.tagName == 'DIV' ){
alert('asdssf')
}
})
</script>

I trying to display message to the browser when
 I click the parent element only, but why this won't.

Do I have to create event handler just for button to
 stop it  from bubbling or  did I typed something wrong.

Hi there, msdsmd sm,dfsadf! If you're only wanting it to show when the div is clicked and not the button inside the div, then you need to use e.target as opposed to e.currentTarget. Because the button is inside the div the event bubbles up to the div when it is clicked which is where the event listener is attached, so it fires.

The answer is to make it so that you're using the event.target which tells us where the event started. So if the starting point was a DIV and not a BUTTON, then fire.

Hope this helps! :sparkles:
