Nevermind. Figured it out :)

I think there may be an issue with one of these test cases: strongEnough([[ 5, 1, 7 ], [ 1, 1, 1 ], [ 4, 1, 2 ] ], 100).

[ 5 + 1 + 7 ],* [ 1 + 1 + 1 ] * [ 4 + 1 + 2 ] returns 273

Building Age is 100 and 1000 - 1% one hundred times returns 0.

0 is less than 273, which would require "Needs Reinforcements!" but it is expecting "Safe!".

var product = "";
var sortedArray = s.sort();
var arrayLength = sortedArray.length;

I have the length of the array stored in a variable though. So if there are 10 items in the array, the arrayLength variable will be 10.

Here's my for loop:

for(i = 0;i < sortedArray[0].length; i++){
  product += sortedArray[0][i] + (i === arrayLength ? ' ': '***' );

}

So I have an if statement that asks if i is equal to the arrayLength variable(max length of the array), then add an empty string. If not add '***'. Wouldn't this work?

So, I'm thinking that my code is correct for this challenge, but I'm getting an error that says "Process terminated. It took longer than 6000ms to complete this task".

Is this something that people have been running into?

Got it. Thanks dude! :)
