wasmuth/test/assoc.js

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

const test = require("tape");

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

test("assoc", (t) => {
  const obj = {a: 1, b: 2, c: 3};
  const ret = assoc("b", 7, obj);
  t.deepEqual(ret, {a: 1, b: 7, c: 3});
  t.is(ret.b, 7);
  t.end();
});
