Converts an `hsl()` 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 toHSLObject = hslStr => {
|
|
const [hue, saturation, lightness] = hslStr.match(/\d+/g).map(Number);
|
|
return { hue, saturation, lightness };
|
|
};
|
|
```
|
|
|
|
```js
|
|
toHSLObject('hsl(50, 10%, 10%)'); // { hue: 50, saturation: 10, lightness: 10 }
|
|
```
