Stitch together two arrays by like-index
Why yet-another zip?
I needed a zip that
- doesn't modify
Arrayprototype - is strongly-typed
- supports currying
npm install @strong-roots-capital/zipimport zip from '@strong-roots-capital/zip'
/* Basic use */
const a = [1, 2, 3]
const b = ['a', 'b', 'c']
console.log(zip(a, b))
//=>[ [ 1, 'a' ], [ 2, 'b' ], [ 3, 'c' ] ]
const zipWithA = zip(a.reverse())
console.log(zipWithA(b))
//=>[ [ 3, 'a' ], [ 2, 'b' ], [ 1, 'c' ] ]Note that the output array will have the same length as a.
