-Convert the number to a string, use `split()` to convert build an array.
+Convert the number to a string, using spread operators in ES6(`[...string]`) build an array.
 Use `Array.map()` and `parseInt()` to transform each value to an integer. 
 
 ```js
-const digitize = n => (''+n).split('').map(i => parseInt(i));
+const digitize = n => [...''+n].map(i => parseInt(i));
 // digitize(2334) -> [2, 3, 3, 4]
 ```
