wasmuth/test/merge.js

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

const test = require("tape");

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

test("merge", (t) => {
  const chain = {chain: 1};
  const o1 = {a: 1, b: 2, d: [chain, {a: 1}]};
  const o2 = {a: "a", c: "c"};
  chain.chain = 2;
  t.deepEqual(merge(o1, o2), {
    a: "a",
    b: 2,
    c: "c",
    d: [{chain: 2}, {a: 1}],
  });
  t.end();
});
