		# [4.0.0](https://github.com/image-js/iobuffer/compare/v3.2.0...v4.0.0) (2018-08-22)


		### Bug Fixes

		* fix test-travis script ([fd74496](https://github.com/image-js/iobuffer/commit/fd74496))
		* remove implied undefined type from InputData ([0040962](https://github.com/image-js/iobuffer/commit/0040962))


		### Chores

		* remove support for Node 4 ([feabb42](https://github.com/image-js/iobuffer/commit/feabb42))


		### Features

		* convert to TypeScript ([b73c748](https://github.com/image-js/iobuffer/commit/b73c748))
		* remove getBuffer method ([39dbc89](https://github.com/image-js/iobuffer/commit/39dbc89))


		### BREAKING CHANGES

		* The `getBuffer` method has been removed. Use `toArray` instead.
		* The IOBuffer constructor is now a named export. Access it with
		`require('iobuffer').IOBuffer` or `import { IOBuffer } from 'iobuffer'`.
		* Removed support for Node 4

		## Usage exemple
		## Usage example

		```js
		const { IOBuffer } = require('iobuffer');

		const io = new IOBuffer();
		// Pointer offset is 0
		io
		.writeChars('Hello world') // Written 11 chars, pointer offset now 11 (->15)
		.writeUint32(42) // Written 32-bit int (default is little-endian), pointer offset now 15
		.setBigEndian() // Switch to big-endian mode
		.writeUint32(24) // Written another 32-bit int, but big-endian, pointer offset now 19
		.mark() // bookmark current pointer offset
		.skip(2) // Pointer offset now 21
		.writeBoolean(true) // Write 0xff, pointer offset now 22
		.reset() // Go to bookmared pointer offset, pointer now 19
		.setLittleEndian() // Go back to little endian mode
		.writeUint16(18) // Write 16-bit unsigned integer in the previously skipped 2 bytes, pointer offset now 21
		.rewind() // Pointer offset now 0
		.getBuffer() // Get a DataView or Buffer (in node.js) over the written part [0-21] of the internal Buffer
		io.writeChars('Hello world') // Write 11 chars, pointer offset now 11 (->15)
		.writeUint32(42) // Write 32-bit int (default is little-endian), pointer offset now 15
		.setBigEndian() // Switch to big-endian mode
		.writeUint32(24) // Write another 32-bit int, but big-endian, pointer offset now 19
		.mark() // Bookmark current pointer offset (19)
		.skip(2) // Pointer offset now 21
		.writeBoolean(true) // Write 0xff, pointer offset now 22
		.reset() // Go to bookmarked pointer offset, pointer offset now 19
		.setLittleEndian() // Go back to little endian mode
		.writeUint16(18) // Write 16-bit unsigned integer in the previously skipped 2 bytes, pointer offset now 21
		.rewind() // Pointer offset back to 0
		.toArray(); // Get a Uint8Array over the written part [0-21] of the internal ArrayBuffer
