        // YOUR CODE HERE
      var obj1 = {foo: 1, bar: 2};

Seems like this code challenge is expecting the use of Chai's include method.

var expect = require('chai').expect

describe('clone', function () {
    var clone = require('./clone.js')
    it('some description string', function () {
        var obj = { a: 1, b: 0 }
        expect(clone(obj)).to.include(obj)
    })
})

Certainly a bit confusing, because there are a number of ways you can assert varying degrees of sameness between two object literals with Chai.
