wasmuth/test/sort.js

Practical, functional utilities that fallback on native implementations as much as possible

const test = require("tape");

const {sort} = require("../");

test("sort", (t) => {
  const arr = ["b", "a", "d", "c"];
  t.deepEqual(sort(arr), ["a", "b", "c", "d"]);
  t.deepEqual(sort()(arr), ["a", "b", "c", "d"]);
  const objs = [{count: 3}, {count: 2}, {count: 9}, {count: 1}];
  t.deepEqual(
    sort(({count: aCount}, {count: bCount}) => aCount - bCount, objs),
    [{count: 1}, {count: 2}, {count: 3}, {count: 9}]
  );
  t.deepEqual(
    sort(({count: aCount}, {count: bCount}) => bCount - aCount)(objs),
    [{count: 9}, {count: 3}, {count: 2}, {count: 1}]
  );
  t.end();
});
