dfcreative/negative-index

Negative-index is a small JavaScript utility for converting negative indices to positive ones, starting from the end of a sequence—similar to how Array.slice handles negative indices. It's useful for developers working with array-like data structures or normalizing offsets, such as time values, where negative indices need to be mapped to their positive equivalents. The package is particularly handy for JavaScript developers needing consistent index normalization across arrays or other indexed collections.
