Touch first

## Implementation

    Touch get first {
      if (this.length > 0) {
        return JS('Touch', '#[0]', this);
      }
      throw new StateError("No elements");
    }

void first= (Touch value)
inherited

Updates the first position of the list to contain `value`.

Equivalent to `theList[0] = value;`.

The list must be non-empty.

## Implementation

    void set first(E value) {
      if (length == 0) throw IterableElementError.noElement();
      this[0] = value;
    }
