Here's my error: We tried your spec with a version of clone.js that DOESN'T work correctly, expecting the test to fail.
Here's my code:
function clone (objectForCloning) { return Object.assign({}, objectForCloning); }
module.exports.clone = clone;
var expect = require('chai').expect;
describe('clone', function () { var clone = require('./clone.js').clone; it('Returns property match', function () {
// YOUR CODE HERE
let obj1 = {
val1: 1,
val2: 2
};
let obj2 = clone(obj1);
//expect({val1:1, val2:2}).to.deep.equal(obj1);
expect(obj2).to.deep.equal(obj1);
});
});
What's the problem?
var expect = require('chai').expect;
describe('clone', function () {
var clone = require('./clone.js').clone;
it('Returns property match', function () {
// YOUR CODE HERE
let obj1 = {
val1: 1,
val2: 2
};
let obj2 = clone(obj1);
//expect({val1:1, val2:2}).to.deep.equal(obj1);
expect(obj2).to.deep.equal(obj1);
});
});
function clone (objectForCloning) {
return Object.assign({}, objectForCloning);
}
module.exports.clone = clone;

- don't modify the code in "clone.js"
- change your declarations to use "var" or "const" instead of "let"
I have no idea why that last one makes a difference, but it does!

20,115 PointsI changed to:
expect(obj2).to.have.property('val1');
expect(obj2).to.have.property('val2');
Same error. (I have a separate test environment, so I know that these pass on my laptop environment.) I'm not sure wgat they're asking for.

20,115 PointsCurrent code:
var expect = require('chai').expect
describe('clone', function () { var clone = require('./clone.js') it('Returns object property match', function () {
// YOUR CODE HERE
var obj1 = {
val1: 1,
val2: 2
};
var obj2 = clone(obj1);
// Add expectation
expect(obj2).to.have.property('val1');
expect(obj2).to.have.property('val2');
})
And in clone.js (no changes):
function clone (objectForCloning) { return Object.assign({}, objectForCloning) }
module.exports = clone

231,248 PointsTry your original code with my suggestions applied (it passed for me).
Robert Glover
20,115 PointsOkay, I'm going to shoot myself. That code now works. Thanks, Steven and James!

20,115 PointsFinley, long time ago. I had to refresh my memory. Treehouse is picky. You have to use var instead of let or const.

11,375 PointsYeah I was only worried that there was some programmatic difference that I wasn't aware of. Thanks for the response

11,375 PointsI would love to know why this worked... after trying several different method combinations and getting this ^^ error, changing my 'let' to 'const' cleared the challenge.
