compared using strict === equality.
The index of the first element in the range to be
searched, inclusive. The default value is -1. Negative values
are taken as an offset from the end of the array.

searched, inclusive. The default value is 0. Negative values
are taken as an offset from the end of the array.
The index of the last occurrence of the value, or -1
if the value is not found.
If start < stop the search will wrap at the front of the array.
