           - It selects all elements with the specified tag name (e.g., div, p, h1, etc.).
           - It returns an HTMLCollection, which is a live collection of all matching elements.
           - Since it returns a collection (not a single element),
             you need to access elements using indexing ([0], [1], etc.) or loop through them.
