JavaScript Regular Expressions in JavaScript Validating a Form Form Validation

regex testing

Now, use the test() method to test the string in text against the regular expression you just created. Remember the test() method returns a true or false value. Return the result of testing the string from the isValidHex method.

Bummer: There was an error with your code: ReferenceError: Can't find variable: hexRegEx

// Type inside this function function isValidHex(text) { let hexRegEx = /^#[a-fA-F0-9]{6}$/; }

const hex = document.getElementById("hex"); const body = document.getElementsByTagName("body")[0]; hexRegEx.test('string'); 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)"; } });

It must be something that doesn't show up without proper formatting. This code should pass task 1 as-is.
