## Description
<section id='description'>
As a reminder, this project is being built upon the following starter project on <a href="https://repl.it/github/freeCodeCamp/boilerplate-mochachai">Repl.it</a>, or cloned from <a href='https://github.com/freeCodeCamp/boilerplate-mochachai/'>GitHub</a>.
<code>strictEqual()</code> compares objects using <code>===</code>.
</section>

## Instructions
<section id='instructions'>
Use <code>assert.strictEqual()</code> or <code>assert.notStrictEqual()</code> to make the tests pass.

</section>

## Tests
<section id='tests'>

```yml
tests:
  - text: All tests should pass.
    testString: getUserInput => $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=5').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
  - text: You should choose the right assertion - strictEqual vs. notStrictEqual.
    testString: 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); })
  - text: You should choose the right assertion - strictEqual vs. notStrictEqual.
    testString: 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); })
  - text: You should choose the right assertion - strictEqual vs. notStrictEqual.
    testString: 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); })
  - text: You should choose the right assertion - strictEqual vs. notStrictEqual.
    testString: 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); })
