# DataView

An interface for working with a raw binary buffer.

The DataView API is exactly as in JavaScript (MDN (opens new window)).

# Constructor

new DataView(buffer: ArrayBuffer, byteOffset?: i32, byteLength?: i32)

Constructs a new DataView on the specified buffer and region.

# Instance members

# Fields

```
readonly buffer: ArrayBuffer
```
The backing buffer.
```
readonly byteLength: i32
```
The length of this view from the start of its buffer.
```
readonly byteOffset: i32
```
The offset of this view from the start of its buffer.

# Methods

```
function toString(): string
```
Returns a string representation of this object.

Endianness defaults to littleEndian = false.
