For () for the vars

Sorry if the title is misleading, had no idea on how to title it.

Here's a var :

         var rects = [
             {x: 32, y: 32, w: 32, h: 32},
             {x: 32, y: 32, w: 32, h: 32},
             {x: 0, y: 0, w: 32, h: 32}

         ], i = 0, r;

Now, I want to do something like this :

 for (nb = 0; nb > 10; nb++;) {
         var rects = [ {x: 32 * nb, y: 32 * nb, w: 32, h: 32} ], i = 0, r;
 }

(Of course this doesn't work).

How can I do this ? Thanks !

Either use Array.from :

let rects = Array.from({length:3} , _=>({x: 32, y: 32, w: 32, h: 32})), i = 0, r;

Or use a traditional for loop:

let rects = [], i = 0, r;

for(let index = 0; index < 3; index++)
  rects[index] = {x: 32, y: 32, w: 32, h: 32};
