import { stableSort } from "https://deno.land/x/30_seconds_of_typescript@v1.0.1/util.ts";
Performs stable sorting of an array, preserving the initial indexes of items when their values are the same. Does not mutate the original array, but returns a new array instead.
Use Array.prototype.map()
to pair each element of the input array with its corresponding index.
Use Array.prototype.sort()
and a compare
function to sort the list, preserving their initial order if the items compared are equal.
Use Array.prototype.map()
to convert back to the initial array items.
