TinkerPop no longer recommends the use of scripts if possible. It is best to simply write Gremlin in the language of your choosing, which for your case is Javascript:

const g = traversal().withRemote(new DriverRemoteConnection('ws://localhost:8182/gremlin'));
g.V().hasLabel('person').values('name').toList()
  .then(names => console.log(names));

That said, you should be able to still submit scripts this way:

const gremlin = require('gremlin');
const client = new gremlin.driver.Client('ws://localhost:8182/gremlin', { traversalSource: 'g' });

const result1 = await client.submit('g.V(vid)', { vid: 1 });
const vertex = result1.first();

Please see the full reference documentation for more information.
