Function expressions and arrows

[odsantos]

Added translation to Function expressions and arrows directory files

[iliakan]

Why did you assign that to me?

[odsantos]

So that you were aware of it and people might contact you if I were unavailable. I'll remove.

[iliakan]

@odsantos I'm really sorry I'm not familiar with Portuguese. So I can't say anything about the translation here. I can merge. Should I?

P.S. You can merge also.
P.P.S. Please ping me for technical stuff and for things that can be solved without knowing Portuguese =)

[odsantos]

@iliakan I am ver sorry I've put you in an uncomfortable situation. No, please don't merge. We need another maintainer for reviewing my PRs. Meanwhile, I expect to be able to leave them open. Thank you. It's nice to communicate with you. Hopefully, until soon.

Files were split. Trying to have translations available as such. Thank you.
