Another question on chai methods for unit testing

So I did my answer again trying to be more specific and create an object, but I'm still not passing. Now I'm really lost. I thought deep copy was supposed to work for something like this.

clone_spec.js 
var expect = require('chai').expect

describe('clone', function () {
    var clone = require('./clone.js').clone;
    var copy = {
      name: "Alex",
      mood: "ugh"
    };
    it('some description string', function () {

        // YOUR CODE HERE
        expect(clone(copy)).to.deep.equal({name: "Alex", mood: "ugh"});
    });
});
clone.js 
function clone (objectForCloning) {
  return Object.assign({}, objectForCloning);
}

module.exports.clone = clone;

You've got the right idea, but place all your added code after the "// YOUR CODE HERE" line.

And you don't need to replicate the object with a literal, you can compare the clone directly to the original. But it will pass just as-is.
