### Number to array of digits
|
|
|
|
use `parseInt()` to get only the integer part of the quotient.
|
|
use `Array.reverse()` to return the array in the same order as the number.
|
|
|
|
```js
|
|
const num2array = (n) =>{
|
|
let arr = [];
|
|
while (n>0) {
|
|
arr.push(n%10);
|
|
n = parseInt(n/10);
|
|
}
|
|
return arr.reverse();
|
|
}
|
|
|
|
// num2array(2334) -> [2, 3, 3, 4]
|
|
``` |
