  .then(user => {
    console.log(user);
  })
  .catch(error => {
    console.error(error);
  });

const User = require('./models/user');

User.where('age').gt(18).lt(30)
  .then(users => {

  })
  .catch(error => {
    console.error(error);
  });

const User = require('./models/user');

User.where('name').regex(/^John/)
