angularjs - How to add limit in meteor query? -

i want limit 2 records using query.

self.helpers({         avalibility: () => {           return setavalibility.find({}).fetch(2);                       }       })

and not working,but same in robomongo working fine.

db.avalibility.find({}).limit(2)

it better not use .fetch() ;)

avalibility: () => {   return setavalibility.find({}, {limit: 2});               }

EEE
