Function alphaLocaleNullable

Returns a comparator function rather than being itself a comparator function. This is just a thin wrapper around the built-in String.prototype.localeCompare(), whose options are the same as Intl.Collator(), which is documented at MDN.

Remarks

As of this writing (January 3, 2023), some Android browsers do not support this function..

Example

import * as A from "flurp/array";
import * as C from "flurp/comparator";

const sortSv = A.sortWith(C.alphaLocaleNullable("sv", { sensitivity: "base" }));
sortSv([null, "a", "ä"]);      // ["a", "ä", null]
