# --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);
}
);
```
