hello  
i am try to create crossWord generator and i have javascript sourc code but i have encountered problem  
i want to convert this code to as3

for(var r = row + 1, c = col, i = 0; r \< grid.length && c \< col + word.length; c++, i++){  
var is\_empty = grid[r][c] == null;  
var is\_intersection = grid[row][c] != null && grid[row][c][‘char’] == word.charAt(i);  
var can\_place\_here = is\_empty || is\_intersection;  
if(!can\_place\_here) return false;  
}

// check to make sure we aren’t overlapping a char (that doesn’t match)  
// and get the count of intersections  
for(var c = col, i = 0; c \< col + word.length; c++, i++){  
var result = canPlaceCharAt(word.charAt(i), row, c);  
if(result === false) return false;  
intersections += result;  
}  
sorry for my bad english

Can you post what you have tried? JS and AS have a lot of similarities 🙂

Ignore the fact that the `for` loop has multiple variables. It is just an expression that evaluates to a number. This…

```
for (var i = 0; i < 10; i++) {

}

```

…is similar to this…

```
var foo = 3;
var bar = 7;

for (var i = 0; i < foo + bar; i++) {

}

```

I’ve never seen that either.(or maybe I forgot it?)  
Its a bit more involved than just a single loop. Its possible to make a nested loop with just a single for loop for example.

I think it was interesting. Like this for example…

```
for (var i = 0,j = 0; i < 4 && j < 4; i++) {
	if (i % 4 == 0) {
		i=0;
		j++;
	}
	trace(i + " " + j);
}

```

well, an _if_ instead of a _for_, but anyway 😃

There’s not a lot that _can’t_ go within the initializer of a loop. E.g. (this is JS, but you get the idea):

```javascript
for(new class _ { constructor(){ Array.of(1,2,3).map(e => console.log(e)) } }; setTimeout(4) < 1500;) 0

```

well, actually, hmm… I’m not sure what that does 🙂
