Jest unexpected token error

[eerwin-foreflight]

Hello!

I am using version 5.1.2 and jest version 26.6.3. When using pdf-merger-js/browser, I was getting an error of "Jest encountered an unexpected token. This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript." when running my jest tests even after properly mocking.

I was eventually able to get around this by adding 'pdf-merger-js': '<rootDir>/node_modules/pdf-merger-js/browser.d.ts', to the moduleNameMapper section in my jest config file.

Also when mocking, I had to do jest.mock('pdf-merger-js') instead of jest.mock('pdf-merger-js/browser') which was a bit confusing.

Just wanted to see if this was expected. I saw no other mentions of having other people having this issue

Sorry, but I don't have time to look into this at the moment.

I hope in the future we can get one implementation for node and the browser to reduce confusion.
