 ### Drone.times() Method

+The `times()` method makes building multiple copies of buildings
 easy. It's possible to create rows or grids of buildings without
 resorting to `for` or `while` loops.
 
 #### Parameters
 
  * numTimes : The number of times you want to repeat the preceding statements.
 
+#### Limitation
+
+For now, don't use `times()` inside a Drone method implementation – only use it at the in-game prompt as a short-hand workaround for loops.

+    d = new Drone(); for ( var i = 0; i < 4; i++ ) {  d.cottage().right(8); }
 
 While this will fit on the in-game prompt, it's awkward. You need to

 above statements is fine for creating a 1-dimensional array of
 structures. But what if you want to create a 2-dimensional or
 3-dimensional array of structures? Enter the `times()` method.
 
 The `times()` method lets you repeat commands in a chain any number of
 times. So to create 4 cottages in a row you would use the following

     cottage().right(8).times(4);

  1. The first 3 calls in the chain ( `cottage()`, `right(8)`, `times(4)` ) build a single row of 4 cottages.
 
- 2. The last 3 calls in the chain ( `fwd(8)`, `left(32)`, `times(5)` ) move the drone forward 8 then left 32 blocks (4 x 8) to return to the original x coordinate, then everything in the chain is repeated again 5 times so that in the end, we have a grid of 20 cottages, 4 x 5.  Normally this would require a nested loop but the `times()` method does away with the need for loops when repeating builds.
