The JavaScript Array length method returns the number of elements in an array. It is a property of the Array object and does not require parentheses to be called. When called on an empty array, it returns 0. If you modify the array by adding or removing elements, the length property will automatically update to reflect the new number of elements. It is important to note that the length property does not necessarily correspond to the highest index in the array, as you can have empty or undefined values in between.
