ZingGrid Internationalization

Problem:
I'm getting this error: Uncaught TypeError: e.split is not a function while using the code available in https://www.zinggrid.com/docs/features/internationalization#custom-language-grid

Solution:
We updated the docs for setting a custom language in ZingGrid. We had some errors in there but it has already been resolved. We fixed the demo too and it's no longer throwing the error you highlighted in the console.
