# --description--

As a reminder, this project is being built upon the following starter project on [Replit](https://replit.com/github/freeCodeCamp/boilerplate-mochachai), or cloned from [GitHub](https://github.com/freeCodeCamp/boilerplate-mochachai/).

`equal()` compares objects using `==`.

# --instructions--

Within `tests/1_unit-tests.js` under the test labelled `#5` in the `Equality` suite, change each `assert` to either `assert.equal` or `assert.notEqual` to make the test pass (should evaluate to `true`). Do not alter the arguments passed to the asserts.

# --hints--

All tests should pass.

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

You should choose the correct method for the first assertion - `equal` vs. `notEqual`.

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'equal',
        'Numbers are coerced into strings with == '
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

You should choose the correct method for the second assertion - `equal` vs. `notEqual`.

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'notEqual',
        ' == compares object references'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

You should choose the correct method for the third assertion - `equal` vs. `notEqual`.

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(
        data.assertions[2].method,
        'equal',
        "6 * '2' is 12 ! It should be equal to '12'"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

You should choose the correct method for the fourth assertion - `equal` vs. `notEqual`.

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(data.assertions[3].method, 'notEqual', "6 + '2' is '62'...");
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
