Converts an `rgb()` color string to an object with the values of each color.
- Use `String.prototype.match()` to get an array of 3 string with the numeric values.
- Use `Array.prototype.map()` in combination with `Number` to convert them into an array of numeric values.
- Use array destructuring to store the values into named variables and create an appropriate object from them.
```js
const toRGBObject = rgbStr => {
const [r, g, b] = rgbStr.match(/\d+/g).map(Number);
return { r, g, b };
};
```
```js
toRGBObject('rgb(255,12,0)'); // {r: 255, g: 12, b: 0}
```
