[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url] [![dependencies][dependencies-image]][dependencies-url]
> Buffer namespace.
## Installation
```bash
npm install @stdlib/buffer
```
## Usage
```javascript
var ns = require( '@stdlib/buffer' );
```
#### ns
Buffer namespace.
```javascript
var o = ns;
// returns {...}
```
The namespace contains the following:
- [`allocUnsafe( size )`][@stdlib/buffer/alloc-unsafe]: allocate a buffer having a specified number of bytes.
- [`Buffer()`][@stdlib/buffer/ctor]: buffer constructor.
- [`arraybuffer2buffer( buf[, byteOffset[, length]] )`][@stdlib/buffer/from-arraybuffer]: allocate a buffer from an ArrayBuffer.
- [`copyBuffer( buffer )`][@stdlib/buffer/from-buffer]: copy buffer data to a new `Buffer` instance.
- [`string2buffer( str[, encoding] )`][@stdlib/buffer/from-string]: allocate a buffer containing a provided string.
- [`reviver( key, value )`][@stdlib/buffer/reviver]: revive a JSON-serialized Buffer.
- [`toJSON( buffer )`][@stdlib/buffer/to-json]: return a JSON representation of a Buffer.
## Examples
```javascript
var objectKeys = require( '@stdlib/utils/keys' );
var ns = require( '@stdlib/buffer' );
console.log( objectKeys( ns ) );
```
