## Usage

```javascript
var toJSON = require( '@stdlib/array/to-json' );
```

#### toJSON( typedarray )

Returns a [JSON][json] representation of a typed array.

```javascript
var Float64Array = require( '@stdlib/array/float64' );

var arr = new Float64Array( [ 5.0, 3.0 ] );

var json = toJSON( arr );
/* returns
    {
        'type': 'Float64Array',
        'data': [ 5.0, 3.0 ]
    }
*/
```

For guidance on reviving a JSON-serialized typed array, see [`reviver()`][@stdlib/array/reviver].

## Notes

-   Supported typed array types:

    -   [`Float64Array`][@stdlib/array/float64]
    -   [`Float32Array`][@stdlib/array/float32]
    -   [`Int32Array`][@stdlib/array/int32]
    -   [`Uint32Array`][@stdlib/array/uint32]
    -   [`Int16Array`][@stdlib/array/int16]
    -   [`Uint16Array`][@stdlib/array/uint16]
    -   [`Int8Array`][@stdlib/array/int8]
    -   [`Uint8Array`][@stdlib/array/uint8]
    -   [`Uint8ClampedArray`][@stdlib/array/uint8c]

-   The implementation provides basic support for custom typed arrays and sets the `type` field to the closest known typed array type.

    ```javascript
    class CustomArray extends Float64Array() {
        constructor( data ) {
            super( data );
        }
    }

    var arr = new CustomArray( [ 5.0, 3.0 ] );

    var json = toJSON( arr );
    /* returns
        {
            'type': 'Float64Array',
            'data': [ 5.0, 3.0 ]
