Change the Title

We have set the title to "CHANGE_THE_TITLE". You have to change it for any other, making sure that document.title returns the new value and the visible title in the TAB itself changes.

Rules

Your code can be any length inside the allowed area. No changes outside of it.

code

<script>
//The code below has already been executed. You can't change it
document.title = "CHANGE_THE_TITLE";

Object.defineProperty(Document.prototype, "title", {set: function()
{
	alert("Sorry! You can't set the title using document.title");
}});
Object.defineProperty = null;
/********** YOUR CODE SHOULD START BELOW THIS LINE **********/






/*********** YOUR CODE SHOULD END ABOVE THIS LINE ***********/
alert(document.title); // We should see a value different than "CHANGE_THE_TITLE"
</script>

Solution

document.title = "Amine CHERRAI";
