• [in] env: The environment that the API is invoked under.
• [in] length: Number of elements in the DataView.
• [in] arraybuffer: ArrayBuffer underlying the DataView.
• [in] byte_offset: The byte offset within the ArrayBuffer from which to start projecting the DataView.
• [out] result: A napi_value representing a JavaScript DataView.

Returns napi_ok if the API succeeded.

This API creates a JavaScript DataView object over an existing ArrayBuffer. DataView objects provide an array-like view over an underlying data buffer, but one which allows items of different size and type in the ArrayBuffer.

It is required that byte_length + byte_offset is less than or equal to the size in bytes of the array passed in. If not, a RangeError exception is raised.

JavaScript DataView objects are described in [Section 24.3][] of the ECMAScript Language Specification.
