Minimal ArrayBufferView compatible with DataVIew methods
// `extends null` isn't necessary but I prefer it.
class BareDataView extends null {
static fromBuffer(...args) {
// construct a new object, passing args to the DataView() constructor
// but use this (i.e. the BareDataView class) to set the prototype
return Reflect.construct(DataView, args, this)
}
}
// Select only the properties we actually want to expose
