Dynamically changing the title of a webpage using JavaScript refers to updating the content of the `<title>` element in the HTML document without reloading the page. This allows developers to modify the page title based on user interaction or other conditions in real-time.

For changing the page title we have two approaches:

Approach 1: Using JavaScript document.title property

This property is used to set or return the current title of the document. The title of the page can be changed by assigning the new title as a string to this property. This will change the title of the website to the preferred title. 

Syntax: 

newPageTitle = 'The title has changed!';
document.title = newPageTitle;

Example: In this example, we use dynamically changes the webpage's title using JavaScript. When the button is clicked, the document.title is updated to "The title has changed!", modifying the page's title instantly.

            document.title = newPageTitle;

Approach 2: Using DOM querySelector() Method

This method selects elements by targeting the <title> tag. Using textContent, it retrieves or updates the page's title. Assigning a new string to textContent dynamically changes the webpage's title to the desired value. 

Syntax: 

newPageTitle = 'The title has changed!';
document.querySelector('title').textContent = newPageTitle;

Example: In this example, we use JavaScript to dynamically change the webpage's title. When the button is clicked, the title updates to "The title has changed!" by modifying the textContent of the <title> element.
