I can't edit my comment any more so I'll just throw another one here. My criticism of `toArray()` is that it's making the rest of the code mostly useless. If you are just going to keep a traditional array around in a cache at all times, and you need to convert your underlying storage to that array any time you iterate then why not just use an array directly? It would be faster, have lower memory usage, and be simpler. The whole point of using a typed array is to avoid the overhead of a normal array, and in your implementation you not only are using a normal array (and all of the downsides of it, larger memory footprint, slower iteration, the JIT still needs to box and check types, etc...), but you are also keeping a copy of that data in a buffer, as well as converting between the 2 quite frequently and inefficiently (your method to build the array in `toArray()` reads each word from the buffer 8 times and just shifts it around a bit each time). It would be easier, faster, have lower memory usage, and simpler to understand to just replace this whole module with `const bitArray = [0, 1, 1, 0, 1, 1, 0, 0]` at any size, since that's basically what it's doing under the hood but with a lot more complexity and overhead.
