JavaScript Regular Expressions in JavaScript Validating a Form Form Validation

Bummer: The hexRegEx variable does not hold a regular expression object.

This is my code: // Type inside this function function isValidHex(text) {

let hexRegEx = /^#[0-9 A-F]{6}$/i.test(text); return hexRegEx;

}

when I preview this everything is working as it should, the background turns green etc.

Why I get this error message when I press the button "Check Work"?

Thank you

app.js
// Type inside this function
function isValidHex(text) {

 let hexRegEx = /^#[0-9 A-F]{6}$/i.test(text);
  return hexRegEx;

}

const hex = document.getElementById("hex");
const body = document.getElementsByTagName("body")[0];

hex.addEventListener("input", e => {
  const text = e.target.value;
  const valid = isValidHex(text);
  if (valid) {
    body.style.backgroundColor = "rgb(176, 208, 168)";
  } else {
    body.style.backgroundColor = "rgb(189, 86, 86)";
  }
});

The challenge wants the variable "hexRegEx" to be a regular expression

so if you just make sure that the variable is let hexRegEx = /^#[0-9 A-F]{6}$/i

you can then return hexRegEx.test(text) and it works the same, but it will also pass the challenge.

Thank you very much Zimri Leijen :)
