Do you feel comfortable learning in your own language or do you prefer English? (For non English-native speakers)

I am native Spanish speaker, although English billingual. However, taking coding courses or classes in Spanish feels odd to me.
I think that part of it is due to that I have always learnt coding stuff in English. And another part is that all coding language itself is in English, and of course the documentation is also.
It feels really odd to hear the name of the functions translated into Spanish. And I also think it is not practical at all, since documentation does not translate the names.
What about you? What is your native language and how do you feel about learning in it?
