## Instructions
<section id='instructions'>
Use template literal syntax with backticks to display each entry of the <code>result</code> object's <code>failure</code> array. Each entry should be wrapped inside an <code>li</code> element with the class attribute <code>text-warning</code>, and listed within the <code>resultDisplayArray</code>.
Use an iterator method (any kind of loop) to get the desired output.
Use an iterator method (any kind of loop) to get the desired output (shown below).

[
'<li class="text-warning">no-var</li>',
'<li class="text-warning">var-on-top</li>',
'<li class="text-warning">linebreak</li>'
