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 template literal syntax with backticks to create an array of list element (<code>li</code>) strings. Each list element's text should be one of the array elements from the <code>failure</code> property on the <code>result</code> object and have a <code>class</code> attribute with the value <code>text-warning</code>. The <code>makeList</code> function should return the array of list item strings.
