[javascript] Convert JSON string to Javascript array

I have an array of arrays which I have planted in the DOM, so that I can reuse it at a later stage to transfer to the server:

[["1","aaaaaa","1"],["2","bbbbbbb","2"],["3","ccccccc","3"]]

If I would like to convert it back into a Javascript array, how would I go about doing this?
