let page = "temp";
function showPage()
{
alert(page); // temp or HTML Page
}
When I tried it, the result was "HTML Page", which makes sense. Is 'page' an object, reserved word, or a constant?
If 'page' is an object, shouldn't I be able to modify it? If it's a reserved word, wouldn't JavaScript throw an error? And if it's a constant, how can I make changes to the DOM using only page access?
One can access the read-only property of the global (window) object, which represents the current HTML/XML/whatever document loaded into the window.
In order to manipulate the DOM, one should utilize DOM manipulation APIs.
edit — To clarify, it is important to note that the "document" property of the window object (or the global variable named "document") is immutable and cannot be changed by JavaScript. However, the value itself is a reference to an object that is mutable in various ways.
