Check the end of string (regular expression)

i am trying to heck if a string (first argument, str) ends with the given target string (second argument, target). function confirmEnding(str, target) { return /target$/.test(str) } Test stringconfirmEnding("Bastian","n") show false. What i am doing wrong? Can i use regular expression as argument of function? ;

If it's always a string, then you can just use String#endsWith

function checkEnd(str, target) {
  return str.endsWith(target);
}

console.log(checkEnd("Bastion", "n"));

If you want to cast target into a regex, but note that this won't escape out any of the special characters in target. i.e. checkEnd('special)',')') will fail due to the regex being invalid:

function checkEnd(str, target) {
  return new RegExp(`${target}$`).test(str);
}

console.log(checkEnd("Bastion", "n"));
