+####Description:
+
+Write a function, persistence, that takes in a positive parameter num and returns its multiplicative persistence, which is the number of times you must multiply the digits in num until you reach a single digit.
+
+####Example:
+
+```js
+ persistence(39) === 3 // because 3*9 = 27, 2*7 = 14, 1*4=4
+                       // and 4 has only one digit
+
+ persistence(999) === 4 // because 9*9*9 = 729, 7*2*9 = 126,
+                        // 1*2*6 = 12, and finally 1*2 = 2
+
+ persistence(4) === 0 // because 4 is already a one-digit number
+```
+
+See [tests in persistent-bugger_test.js](https://github.com/AlexVvx/code-wars/tree/master/katas/persistent-bugger/persistent-bugger_test.js)

+Good luck
