If you do a lot of coding in popular software languages like Java and Python, eventually you will run into open source projects whose comments and documentation and issues are all in Mandarin. There are also Chinese versions of Stack Overflow, where I have to use Google Translate to read the discussion threads.
It will always be more difficult to understand a language which is not your first, but if there's a language on this planet that would be useful to learn aside from English, it's Mandarin.
I am personally not familiar with any differences in major frameworks between Chinese software ecosystems and American/European ones. But that is surely just my ignorance as a foreigner. Please let us know what you find.
