Hello. I have issue with returning all results to variable in JS. I build simple test, but when use

const SRL = require('srl');
const query = new SRL(query);
console.log(query.exec(query));

In console recieve:

[ 'What',
  'What',
  index: 0,
  input: 'What is Lorem Ipsum? ... ' ]

But what about all other? And why What is 2 times?
Thanks.
