DOMTokenList.item()

The item() method of the DOMTokenList interface returns an item in the list, determined by its position in the list, its index.

Note: This method is equivalent as the bracket notation. So list.item(i) is the same as list[i].

Inputs: index A number representing the index of the item you want to return. If it isn’t an integer, only the integer part is considered.

Returns: A string representing the returned item, or null if the number is greater than or equal to the length of the list.

Exceptions: TypeError Thrown if the index cannot be converted to an integer.
