While and Comment Differences

I just thought I'd share what I thought about a couple of differences between JavaScript and VBScript.

Loop Difference

I think it's better that JavaScript doesn't have a do...until loop. The do...until loop seems kind of superfluous to me, since the same can easily be accomplished with a while loop. For example, these two are equivalent:

Do Until (x)
 ' do something
Loop

while (!x) {
 // do something
}

Comments Difference

Notice the difference between the comments in the examples above. That was the other difference I wanted to mention. I tend to think that faster is better, and it's faster to type the single quote (') than it is to type 2 forward slashes (//). On the other hand, JavaScript provides for making part of a line a comment anywhere in the code, like this:

if (x /* == true */)

As you can see, the end parenthesis ")" comes after the comment. I don't know if VBScript provides any way of making comments like that. Does anybody else know?
