"Create Strings using Template Literals" fails with correct output

Tell us what’s happening:
Although the output seems right to me, the last test Template strings were used fails saying that

// running test
Invalid regular expression flags
// tests completed

I’m confused to whether I am not seeing something obvious or this is a potential bug?

Your code so far

const result = {
  success: ["max-length", "no-amd", "prefer-arrow-functions"],
  failure: ["no-var", "var-on-top", "linebreak"],
  skipped: ["id-blacklist", "no-dup-keys"]
function makeList(arr) {
  "use strict";

  // change code below this line
  const resultDisplayArray = arr.map(function(item) {
    return `<li class="text-warning">${item}</li>`;
  // change code above this line

  return resultDisplayArray;
 * makeList(result.failure) should return:
 * [ <li class="text-warning">no-var</li>,
 *   <li class="text-warning">var-on-top</li>, 
 *   <li class="text-warning">linebreak</li> ]
const resultDisplayArray = makeList(result.failure);

Link to the challenge:

A quick search of the forum for “Template Literal” would have given you many previous threads discussing the fact there currently is a bug in the tests, which causes correct code to fail the tests.

Okay, thanks for letting me know.

Bug fixed; Thanks guys

Why does my code not work? Is the bug not fixed or am I doing something wrong?

const resultDisplayArray = arr.map((item)=> <li class=text-warning>${item}</li>);
