Converts the values of RGB components to a hexadecimal color code.
|
|
|
|
- Convert given RGB parameters to hexadecimal string using bitwise left-shift operator (`<<`) and `Number.prototype.toString()`.
|
|
- Use `String.prototype.padStart()` to get a 6-digit hexadecimal value.
|
|
|
|
```js
|
|
const RGBToHex = (r, g, b) =>
|
|
((r << 16) + (g << 8) + b).toString(16).padStart(6, '0');
|
|
```
|
|
|
|
```js
|
|
RGBToHex(255, 165, 1); // 'ffa501'
|
|
```
