Generates a random hexadecimal color code. Generates a random hexadecimal color code.
Use `Math.random` to generate a random number and limit that number to fall in between 0 and 16 using `Math.floor`. Use the generated random number as index to access a character from 0 to F. Append it to `color` till the length is not `7`. 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 ```js
const randomHexColorCode = () => { const randomHexColorCode = () => '#'+(Math.random()*0xFFFFFF<<0).toString(16);
let color = '#';
while(color.length < 7) color += '0123456789ABCDEF'[Math.floor(Math.random() * 16)];
return color;
}
// randomHexColorCode() -> "#e34155" // randomHexColorCode() -> "#e34155"
// randomHexColorCode() -> "#fd73a6" // randomHexColorCode() -> "#fd73a6"
// randomHexColorCode() -> "#4144c6" // randomHexColorCode() -> "#4144c6"
