Suggestion: deprecate the unzip function in favor of the zip function

Is your feature request related to a problem? Please describe.

The current zip() is upward compatible with unzip(). Both just transpose a 2D array.

import { zip } from "https://deno.land/[email protected]/collections/zip.ts";
import { unzip } from "https://deno.land/[email protected]/collections/unzip.ts";

const target = [[0, "a"], [1, "b"]];

const zipped = zip(...target);
console.log(zipped); // [ [ 0, 1 ], [ "a", "b" ] ]

const unzipped = unzip(target);
console.log(unzipped); // [ [ 0, 1 ], [ "a", "b" ] ]

How about deprecating unzip in favor of zip?

Describe alternatives you've considered

The only difference between zip and unzip is that when they receive multiple arrays of different lengths, they align to the shortest or the longest.

import { zip } from "https://deno.land/[email protected]/collections/zip.ts";
import { unzip } from "https://deno.land/[email protected]/collections/unzip.ts";

const target = [[0, "a"], [1]];

const zipped = zip(...target);
console.log(zipped); // [ [ 0, 1 ] ]

const unzipped = unzip(target);
console.log(unzipped); // [ [ 0, 1 ], [ "a", undefined ] ]

In Python, there is no unzip function, but instead there is a itertools.zip_longest function. How about deprecating unzip, adding zipLongest and resolving #1203?

I think zip and unzip should be left separate even if they'd end up pointing at the same function, because they are different conceptually. zip(*zipped_list) doesn't read "unzip" to me, and probably never will, having worked with Python for many years. I see no reason why deno_std would take any inspiration from Python of all languages.

@ayame113, do you still have this opinion? I'm slightly in favour of keeping unzip() as it is. Though, I'm mostly impartial.

deno_std's zip function takes a variable length argument instead of two arguments. There is a big difference between zip and unzip when the zip function takes 2 arguments, but not much difference between them when the zip function takes 3 or more arguments. For this reason, I thought it would be possible to use Python's naming conventions.
That being said, I don't have a strong opinion on this either, so feel free to leave the unzip naming as is. Let's close this issue. 👍
