So I was writing a small helper method to convert numbers into a valid money format ($xx,xxx.xx) using .toLocaleString(). Everything works as expe
$xx,xxx.xx
.toLocaleString()
Based on this issue it appears that it was decided that shipping node.js with internationalization would make it too large. You can npm install intl and require that, and it will replace toLocaleString with a version that works.
npm install intl
toLocaleString
