Difference between subarray() and slice() ?

Hi Nicholas,

You describe the subarray method, which for all intents and purposes seems to have identical behavior to the slice method originally from Array. For instance, slice supports the same signature, they both maintain the original array type…

Upon more careful doc reading, it seems subarray creates a sort of view on the original dataset, so modifying the result’s cells would also impact the original typed array? If so, that'd likely be the difference I'm looking for, but it doesn't appear / stand out in your text.
