## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var reviver = require( '@stdlib/array/reviver' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### reviver( key, value )
|
||
|
|
|
||
|
|
Revives a JSON-serialized typed array.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var parseJSON = require( '@stdlib/utils/parse-json' );
|
||
|
|
|
||
|
|
var str = '{"type":"Float64Array","data":[5,3]}';
|
||
|
|
|
||
|
|
var arr = parseJSON( str, reviver );
|
||
|
|
// returns <Float64Array>[ 5.0, 3.0 ]
|
||
|
|
```
|
||
|
|
|
||
|
|
For details on the JSON serialization format, see [`toJSON()`][@stdlib/array/to-json].
