Sometimes you just want a sub dataview and that is currently pretty annoying to do:

```js
new DataView(dataview.buffer, dataview.byteOffset + offset, length)

```

a `.slice` method seems way more logical. Also you don't want people slicing the buffer as that creates a copy.

So am I the only one longing for this.

I wouldn't call it `.slice()`, since as you mentioned, that has the meaning of "copy and create new", but it certainly wouldn't be unreasonable to add a `.subview()` method for parity with `TypedArray.prototype.subarray()`.

I agree that would be a better name
