+# ArrayBuffer
+
+The `Napi::ArrayBuffer` class corresponds to the
+[JavaScript `ArrayBuffer`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer)
+class.
+
+## Methods
+
+### New
+
+Allocates a new `Napi::ArrayBuffer` instance with a given length.
+
+```cpp
+static Napi::ArrayBuffer Napi::ArrayBuffer::New(napi_env env, size_t byteLength);
+```
+
+- `[in] env`: The environment in which to create the `Napi::ArrayBuffer` instance.
+- `[in] byteLength`: The length to be allocated, in bytes.
+
+Returns a new `Napi::ArrayBuffer` instance.
+
+### New
+
+Wraps the provided external data into a new `Napi::ArrayBuffer` instance.
+
+The `Napi::ArrayBuffer` instance does not assume ownership for the data and
+expects it to be valid for the lifetime of the instance. Since the
+`Napi::ArrayBuffer` is subject to garbage collection this overload is only
+suitable for data which is static and never needs to be freed.
+
+```cpp
+static Napi::ArrayBuffer Napi::ArrayBuffer::New(napi_env env, void* externalData, size_t byteLength);
+```
+
+- `[in] env`: The environment in which to create the `Napi::ArrayBuffer` instance.
+- `[in] externalData`: The pointer to the external data to wrap.
+- `[in] byteLength`: The length of the `externalData`, in bytes.
+
+Returns a new `Napi::ArrayBuffer` instance.
+
+### New
+
+Wraps the provided external data into a new `Napi::ArrayBuffer` instance.
+
+The `Napi::ArrayBuffer` instance does not assume ownership for the data and
+expects it to be valid for the lifetime of the instance. The data can only be
+freed once the `finalizeCallback` is invoked to indicate that the
+`Napi::ArrayBuffer` has been released.
+
+```cpp
+template <typename Finalizer>
+static Napi::ArrayBuffer Napi::ArrayBuffer::New(napi_env env,
+                       void* externalData,
+                       size_t byteLength,
+                       Finalizer finalizeCallback);
+```
+
+- `[in] env`: The environment in which to create the `Napi::ArrayBuffer` instance.
+- `[in] externalData`: The pointer to the external data to wrap.
+- `[in] byteLength`: The length of the `externalData`, in bytes.
+- `[in] finalizeCallback`: A function to be called when the `Napi::ArrayBuffer` is
+  destroyed. It must implement `operator()`, accept a `void*` (which is the
+  `externalData` pointer), and return `void`.
+
+Returns a new `Napi::ArrayBuffer` instance.

+  `externalData` pointer) and `Hint*`, and return `void`.
+- `[in] finalizeHint`: The hint to be passed as the second parameter of the
+  finalize callback.
+
+Returns a new `Napi::ArrayBuffer` instance.
+
+### Constructor
+
+Initializes an empty instance of the `Napi::ArrayBuffer` class.
+
+```cpp
+Napi::ArrayBuffer::ArrayBuffer();
+```
+
+### Constructor
+
+Initializes a wrapper instance of an existing `Napi::ArrayBuffer` object.
+
+```cpp
+Napi::ArrayBuffer::ArrayBuffer(napi_env env, napi_value value);
+```
+
+- `[in] env`: The environment in which to create the `Napi::ArrayBuffer` instance.
+- `[in] value`: The `Napi::ArrayBuffer` reference to wrap.
+
+### ByteLength
+
+```cpp
+size_t Napi::ArrayBuffer::ByteLength() const;
+```
+
+Returns the length of the wrapped data, in bytes.
+
+### Data
+
+```cpp
+T* Napi::ArrayBuffer::Data() const;
+```
+
+Returns a pointer the wrapped data.
