# Slightly DRYer, but any caveats?

My code for the fifth While loop exercise is shown below and seems to work properly from what I can tell. Joel had slightly more code than this in the video and reversed the order of lines within the loop. Any hidden issues with my version? thanks! Steve

```i = 0;
while (i != 8) {
i = Math.floor(Math.random() * 10);
text += i + ' ';
}
print(text);
```

Joel's version has slightly less code (by one line) since the "do" style loop doesn't require the value of "i" to be preset like your ordinary "while" does. Also, both loops require "text" to be preset to an empty string but that's not shown in the code above.

Otherwise, the code content inside the loop appears to be the same (including the order), so the functionality will be identical.

Thanks for your response Steven! Just to be clear, I am comparing my included code directly to Joel's solution for the "while" loop (not do-while) fifth example, which I am now copying in below:

Joel's code solution

```i = Math.floor(Math.random() * 10);
while (i != 8) {
text += i + ' ';
i = Math.floor(Math.random() * 10);
}
text += i;

print(text)
```

Seems like you are saying nothing wrong with my version, which is what I wanted to check, so thanks!

Steve

Yes, your version is a step between the instructor's two versions in regards to compactness. All three function exactly alike.
