@ -5,15 +5,14 @@ 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 | 0).toString(16);
return '#' + (n.length !== 6
? (Math.random() * 0xf | 0).toString(16) + n : n);
};
const randomHexColorCode = () => {
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"
randomHexColorCode(); // "#e34155"
randomHexColorCode(); // "#fd73a6"
randomHexColorCode(); // "#4144c6"
```
