-Generates a random hexadecimal color code.
-
-Use `Math.random` to generate a random 24-bit(6x4bits) hexadecimal number. Use bit shifting and then convert it to an hexadecimal String using `toString(16)`.
-
-```js
-const randomHexColor = () => {
-  let n = (Math.random() * 0xfffff | 0).toString(16);
-  return '#' + (n.length !== 6
-        ? (Math.random() * 0xf | 0).toString(16) + n : n);
-};
-```

-```js
-randomHexColorCode() // "#e34155"
-randomHexColorCode() // "#fd73a6"
-randomHexColorCode() // "#4144c6"
