Hi, now that node::Buffer is a ArrayBufferView https://github.com/nodejs/node/blob/master/src/node_buffer.cc#L202 which covers all javascript typed arrays https://v8docs.nodesource.com/node-8.0/d5/dbb/classv8_1_1_typed_array.html, the Buffer::New's don't have a way to make Float64Array or any of the other typed arrays. For typed arrays passed from javascript the native code the type is known. Constructing a node::Buffer in the native code has no way to distinguish type on the javascript side.

Before it was one-to-one; UintArray to node::Buffer. Isn't there something like a node::Buffer::NewFloa64Array(...); needed for each type?
