Re: [Flattening Arrays](http://forum.kirupa.com/t/javascript-tip-of-the-day/641803/85) Interesting article but I have a few questions. First, in your ticTacToeBoard example, will the original array reflect any changes that are made to the flattened array? Second I assume this it just a one way operation in that once the array is flattened there is no way to go back to the original array. That is correct right? ---
