## 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>equal()</code> compares objects using <code>==</code>.
</section>
## Instructions
<section id='instructions'>
Use <code>assert.equal()</code> or <code>assert.notEqual()</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=4').then(data => {assert.equal(data.state,'passed'); }, xhr => { throw new Error(xhr.responseText); })
- text: You should choose the right assertion - equal vs. notEqual.
testString: 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); })
- text: You should choose the right assertion - equal vs. notEqual.
testString: 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); })
- text: You should choose the right assertion - equal vs. notEqual.
testString: 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); })
- text: You should choose the right assertion - equal vs. notEqual.
testString: 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); })
