Intl.js VS react-intl

I'm using React-Intl with webpack and I need the Intl shim to support Safari and IE, but I don't want to load it for browsers that already support the Intl spec.

It was possible to work with Intl with or without Hermes all the time, you just had to install a polyfill (https://github.com/andyearnshaw/Intl.js) for it, I've been using it for at least 3 years, and didn't have any issues.

I am developing an application with react/redux, and I started using library react-intl for formatting messages and dates.

I have been struggling mocking React-Intl library with Jest because I'm having this error when I run tests:

So I defined messages
