Invert an object, such that keys become values and values become keys, according to a transform function.

A bidirectional Map/WeakMap implementation with the same API as an ES6 Map/WeakMap!

KombiN is a library for bijectively mapping all ordered pairs from two finite sets into a single linear index. It orders pairs by ascending weight (sum of indices) using a three-region zig-zag algorithm, enabling O(1) bidirectional lookups between pairs a
