zippy is a tiny library that implements the zip and the more general zipWith. It was factored out of the "hempwick" project, since it's the only part of it I've used regularly and the project was too big for me to maintain.
npm install zippy
Returns a list with elements (x_i, y_i, ...). For example:
> zippy.zip([1, 2, 3], [1, 4, 9])
[[1, 1], [2, 4], [3, 9]]
zip may take more than two arguments.
protip:
> var transpose = function(a) { return zippy.zip.apply(null, M); };
zipWith is a more general form of zip, which takes a function that "does
something" with each set of x_i, y_i. In fact, zip is implemented with
zipWith! For an example:
> zippy.zipWith(function(x,y) {return x+y;}, [1, 2, 3], [3, 2, 1])
[4, 4, 4]
npm test
