unescaped user input

[kylegrover]

typing ie / or + into the 'Search country' field crashes the app problem occurs @ index.js:372 new RegExp(countrySearchQuery.trim(), 'i')

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions suggests this code

function escapeRegExp(string){
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Very good point! Thanks @kylegrover. It should be fixed now.
