I started my self-study javascript 10 days ago and I have to do one exercise. I 've read related articles through several sources also incl javascript manual. I don't have too much programming knowledge, so what I did is somehow not so good. Anyway I write here because I hope that somebody could explain me , how should it be done. So tks in advance. The exercise is :

Complete the below javascript: Find and print all the numbers in the sentence in one table. If there are no numbers in the sentence, print "No numbers!". Try checking the sentence for numbers using the test () method:

```
var sentence = "J07ku7 k1rj01774v47 54n0j4 num3r0174 käy77ä3n.";

function print numbers () {
  ### put your code here ###    
}

```

**Example output**

```
0,7,7,1,0,1,7,7,4,4,7,5,4,0,4,3,0,1,7,4,7,7,3

```
