Because that is not valid javascript ?

And thats not valid javascript either. Both also create a problem : What
are the non-js parts (like "{ inc x, step}" or "that[x]) actually supposed
to mean ? I can /guess/, but I should not be forced to do that ...
In short: When posting examples its a good idea to use a /working/ one. It
makes it much easier to understand.
Like this:
x=0
while (x <5) {
..
..
// do stuf
..
..
x += 2
}
And yes, that works.
Now ask yourself: What /good/ does it do to smear a "for" loop out over
three seperate lines, with the incrementing of the loopcounter being as far
away from its initialisation & checking as possible ?
Compare it with a "for" loop:
for (x=0; x<5; x += 2 {
..
..
// do stuf
..
..
}
Here everything that matters to the loop is close together - on a single
line even - , making it much harder to make a "what was the loopcounter
variable and by how much should it advance again ?" mistakes.
But, bottom line: use the loop you like best, as it doesn't really matter to
the code itself. (below the surface the "for", "while", "do while" and "do
until" loops work exactly the same).

Rudy Wieser
