Just using .buffer works in these cases, but I’m not sure we should include it in our documentation like this – most of the time when you’re doing this, you’ll want to consider .byteLength and .byteOffset as well?

I just modified the samples to work without thinking to much about it. Printing a Float64Array formatted as 'hex' is usually not a typical use. I will update the samples to use also .byteLength and .byteOffset but I'm not sure if doc of randomFillSync() is the right place to show how to work with typed arrays.

Correct return type of `crypto.randomFillSync()` which is of same type as passed as `buffer` argument. Correct samples for `randomFill()` and `randomFillSync()` using a `TypeArray` or `DataView` as these types don't support `.toString(encoding)`.
