Buffer objects

Overview of buffer types

Duktape provides the following buffer and buffer-related types:

Type	Standard	Duktape version	Description
Plain buffer	No Duktape specific	1.0	Plain, primitive buffer value (not an object), similar to how a plain string relates to a String object
Duktape.Buffer object	No Duktape specific	1.0	Object wrapped plain buffer, similar to how a String object relates to a plain string
Node.js Buffer object	No Node.js-like	1.3	Object with Node.js Buffer API
ArrayBuffer object	Yes Khronos/ES6	1.3	Standard object type for representing a byte array
DataView, typed array objects	Yes Khronos/ES6	1.3	View objects to access an underlying ArrayBuffer

See buffers.rst for a detailed discussion, including a detailed table of buffer types and their properties.

Working with buffers

Buffer values work in both C and Ecmascript code:

For Ecmascript code most of the behavior is defined in the relevant API standards, with exceptions for Duktape-specific features like mixing different buffer types.
For C code there are API calls to work with plain buffers and buffer objects.

See How to work with buffers for examples.
