NodeList.item()

Returns a node from a NodeList by index. This method doesn’t throw exceptions as long as you provide arguments. A value of null is returned if the index is out of range, and a TypeError is thrown if no argument is provided.

In JavaScript, instead of calling nodeList.item(index), you can also access the index directly, like nodeList[index].

Inputs: index The index of the node to be fetched. The index is zero-based.

Returns: The indexth node in the nodeList returned by the item method.
