## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var reviver = require( '@stdlib/buffer/reviver' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### reviver( key, value )
|
||
|
|
|
||
|
|
Revives a JSON-serialized [`Buffer`][@stdlib/buffer/ctor].
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var parseJSON = require( '@stdlib/utils/parse-json' );
|
||
|
|
|
||
|
|
var str = '{"type":"Buffer","data":[5,3]}';
|
||
|
|
|
||
|
|
var buf = parseJSON( str, reviver );
|
||
|
|
// returns <Buffer>[ 5, 3 ]
|
||
|
|
```
|
||
|
|
|
||
|
|
For details on the JSON serialization format, see [`toJSON()`][@stdlib/buffer/to-json].
