wasmuth/test/reject.js

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

const test = require("tape");

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

test("reject", (t) => {
  const isOdd = (n) => n % 2 === 1;
  t.deepEqual(reject(isOdd, [1, 2, 3, 4]), [2, 4]);
  t.deepEqual(reject(isOdd, {a: 1, b: 2, c: 3, d: 4}), {b: 2, d: 4});
  t.end();
});
