--description--

As a reminder, this project is being built upon the following starter project on Replit, or cloned from GitHub.

strictEqual() compares objects using ===.

--instructions--

Within tests/1_unit-tests.js under the test labelled #6 in the Equality suite, change each assert to either assert.strictEqual or assert.notStrictEqual to make the test pass (should evaluate to true). Do not alter the arguments passed to the asserts.

--hints--

All tests should pass.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the first assertion - strictEqual vs. notStrictEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'notStrictEqual',
        'with strictEqual the type must match'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the second assertion - strictEqual vs. notStrictEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(data.assertions[1].method, 'strictEqual', '3*2 = 6...');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the third assertion - strictEqual vs. notStrictEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(
        data.assertions[2].method,
        'strictEqual',
        "6 * '2' is 12. Types match !"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the fourth assertion - strictEqual vs. notStrictEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(
    (data) => {
      assert.equal(
        data.assertions[3].method,
        'notStrictEqual',
        'Even if they have the same elements, the Arrays are notStrictEqual'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
