 ### Capitalize first letter
 
-Use `slice(0,1)` and `toUpperCase()` to capitalize first letter, `slice(1)` to get the rest of the string.
+Use destructuring and `toUpperCase()` to capitalize first letter, `...rest` to get array of characters after first letter and then `Array.join('')` to make it a string again.
 Omit the `lowerRest` parameter to keep the rest of the string intact, or set it to `true` to convert to lower case.
 
 ```js
-const capitalize = (str, lowerRest = false) =>
-  str.slice(0, 1).toUpperCase() + (lowerRest ? str.slice(1).toLowerCase() : str.slice(1));
+const capitalize = ([first,...rest], lowerRest = false) =>
+  first.toUpperCase() + (lowerRest ? rest.join('').toLowerCase() : rest.join(''));
+// capitalize('myName') -> 'MyName'
 // capitalize('myName', true) -> 'Myname'
 ```
