### randomHexColor
|
|
|
|
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);
|
|
};
|
|
// randomHexColorCode() -> "#e34155"
|
|
// randomHexColorCode() -> "#fd73a6"
|
|
// randomHexColorCode() -> "#4144c6"
|
|
```
