    • [in] env: The environment that the API is invoked under.
    • [in] typedarray: napi_value representing the TypedArray whose properties to query.
    • [out] type: Scalar datatype of the elements within the TypedArray.
    • [out] length: The number of elements in the TypedArray.
    • [out] data: The data buffer underlying the TypedArray adjusted by the byte_offset value so that it points to the first element in the TypedArray. If the length of the array is 0, this may be NULL or any other pointer value.
    • [out] arraybuffer: The ArrayBuffer underlying the TypedArray.
    • [out] byte_offset: The byte offset within the underlying native array at which the first element of the arrays is located. The value for the data parameter has already been adjusted so that data points to the first element in the array. Therefore, the first byte of the native array would be at data - byte_offset.

    Returns napi_ok if the API succeeded.

    This API returns various properties of a typed array.

    Warning: Use caution while using this API since the underlying data buffer is managed by the VM.
