JavaScript Regular Expressions in JavaScript Validating a Form Form Validation

In Challenge 1, I'm getting an error 'The hexRegEx variable does not hold a regular expression'.

The function is isValidHex. Any help is appreciated.

app.js
// Type inside this function
function isValidHex(text) {
  var RegEx = /^#[\da-z]{6}$/i;
  var hexRegEx = text.match(/^#[\da-z]{6}$/i);
}

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)";
  }
});

Your RegEx variable's value is correct. Rename RegEx to hexRegEx (remove the old hexRegEx altogether) and Challenge 1 should pass.

Challenge 2 requires the use of test().

Thanks, Sean! I was overthinking this and trying to place the value of text into hexRegEx.
