Full Stack JavaScript Techdegree Graduate 16,113 PointsRegexp problem
Answer to my solution is that; my solution is not an regexp object.
// Type inside this function
function isValidHex(text) {
const hexRegEx = /^(£|#){1}[A-F0-9]{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)";
}
});

231,236 PointsThe regex expression is the part starting with the "/" and and ending with "/i". For task 2, you can invoke the method on "hexRegEx" as part of the return statement. Also:
- you don't need an explicit repeat count for a single character
- the token for a color is always "#", no matter what your country uses for currency
const hexRegEx = /^#[A-F0-9]{6}$/i;
