For details on the JSON serialization format, see @stdlib/array-to-json.

Examples

var Float64Array = require( '@stdlib/array-float64' );
var parseJSON = require( '@stdlib/utils-parse-json' );
var typedarray2json = require( '@stdlib/array-to-json' );
var reviveTypedArray = require( '@stdlib/array-reviver' );

var arr = new Float64Array( [ 5.0, 3.0 ] );
var str = JSON.stringify( typedarray2json( arr ) );
// returns '{"type":"Float64Array","data":[5,3]}'

var out = parseJSON( str, reviveTypedArray );
if ( out instanceof Error ) {
    throw out;
}
console.log( out );
// => <Float64Array>[ 5.0, 3.0 ]
