--- title: digitize tags: math,array,beginner --- Converts a number to an array of digits. Convert the number to a string, using the spread operator (`...`) to build an array. Use `Array.prototype.map()` and `parseInt()` to transform each value to an integer. ```js const digitize = n => [...`${n}`].map(i => parseInt(i)); ``` ```js digitize(123); // [1, 2, 3] ```
