Generates a random hexadecimal color code.
|
|
|
|
- Use `Math.random()` to generate a random 24-bit (6 * 4bits) hexadecimal number.
|
|
- Use bit shifting and then convert it to an hexadecimal string using `Number.prototype.toString()`.
|
|
|
|
```js
|
|
const randomHexColorCode = () => {
|
|
let n = (Math.random() * 0xfffff * 1000000).toString(16);
|
|
return '#' + n.slice(0, 6);
|
|
};
|
|
```
|
|
|
|
```js
|
|
randomHexColorCode(); // '#e34155'
|
|
```
