import breakpoint from './modules/breakpoint.js';

let config = {
  // media query
  // type: string
  // required
  query: '(min-width: 1024px)',

  // callback to call when the query result is true
  // type: function
  // required
  success: () => console.log('Window width is above 1024px'),

  // function to call when the query result is false
  // type: function
