@ -5,7 +5,11 @@ 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 = () => '#'+(Math.random()*0xFFFFFF<<0).toString(16);
const randomHexColor = () => {
let n = (Math.random()*0xfffff|0).toString(16);
return '#' + (n.length !== 6
? (Math.random()*0xf|0).toString(16) + n : n);
}
// randomHexColorCode() -> "#e34155"
// randomHexColorCode() -> "#fd73a6"
// randomHexColorCode() -> "#4144c6"
