Confirm the Ending using regex

Tell us what’s happening:

I used a regex to solve this, but I keep getting an error saying testRegex.test is not a function. I read the help and understand the other method, but am also curious - what am I doing wrong with the regex usage?

Your code so far


function confirmEnding(str, target) {

  let testRegex = '/' + target + '$/';

  return testRegex.test(str);

}

confirmEnding("Bastian", "n");

regular expression /something/ and strings "/something/" are not the same thing.

use the Regexp() constructor instead and use target as your argument
