# elementAt method

Length elementAt (int index)
override

Returns the `index`th element.

The `index` must be non-negative and less than length. Index zero represents the first element (so `iterable.elementAt(0)` is equivalent to `iterable.first`).

May iterate through the elements in iteration order, ignoring the first `index` elements and then returning the next. Some iterables may have more a efficient way to find the element.

## Implementation

    Length elementAt(int index) => this[index];
