+### Number to array to 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]
+```
