Package Exports

array-hyper-unique

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (array-hyper-unique) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

array-hyper-unique

Get unique values of an array. Really, like deeply unique.

API

this module base on arr-unique
but rewrite to typescript and bug fix
also add option control
see _data.ts and test.test.ts
