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

    Returns napi_ok if the API succeeded.

    This API creates a JavaScript TypedArray object over an existing ArrayBuffer. TypedArray objects provide an array-like view over an underlying data buffer where each element has the same underlying binary scalar datatype.

    It’s required that (length * size_of_element) + byte_offset should be <= the size in bytes of the array passed in. If not, a RangeError exception is raised.

    JavaScript TypedArray objects are described in [Section 22.2][] of the ECMAScript Language Specification.
