My current regex is /^[A-Za-z0-9_-]\w{5,23}$/ and it matches everything but the hyphen. I tried \- and still no soup. Anybody with a little more experience know how to catch the hyphen?

let errmsg = document.querySelector("#error");
let input_box = document.querySelector("#password");

function checkPassword(value) { 
  var regex =  /^[A-Za-z0-9_-]\w{5,23}$/;
  if (!regex.test(value.target.value))
  {
    console.log(value.target.value);
    errmsg.style.display = 'block';
    input_box.style.borderColor = 'red';
  }
  else
  {
    errmsg.style.display = 'none';
    input_box.style.borderColor = 'black';
  }
}
input_box.addEventListener('input', checkPassword);
