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 randomHexColorCode = () => {
let n = (Math.random() * 0xfffff * 1000000).toString(16);
return '#' + n.slice(0, 6);
};
```
```js
randomHexColorCode(); // '#e34155'
```
