Use .toEndWith when checking if a string ends with a given string suffix

import {
  defineExpect,
  not,
  test,
  toEndWith,
} from "https://deno.land/x/unitest@$VERSION/mod.ts";

const expect = defineExpect({
  matcherMap: {
    toEndWith,
  },
  modifierMap: {
    not,
  },
});

test("passes when value is ends with given string", () => {
  expect("hello world").toEndWith("world");
  expect("hello world").not.toEndWith("hello");
});
