Say I have a file foo.js that was committed some time ago. I would like to
simply find the commit where this file was first added.
After reading the answers and my own tinkering, this works for me
git log --follow --diff-filter=A --find-renames=40% foo.js

Here's simpler, "pure Git" way to do it, with no pipeline needed:
git log --diff-filter=A -- foo.js
Check the documentation. You can do the same thing for Deleted, Modified, etc.
https://git-scm.com/docs/git-log#Documentation/git-log.txt---diff-filterACDMRTUXB82308203
I have a handy alias for this, because I always forget it:
git config --global alias.whatadded 'log --diff-filter=A'
This makes it as simple as:
git whatadded -- foo.js
The below one liner will recursively search through sub directories of the $PWD for foo.js without having to supply and absolute or relative path to the file, nor will the file need to be in the same directory as the $PWD
git log --diff-filter=A -- **foo.js
回答2:
git log --oneline -- foo.js | tail -n 1

The following may not be not of you interest, but I think it will help you in future and is part of debugging ecosystem in Git:
You can use git-blame to show what revision and author last modified each line of a file, especially file annotation. Visit https://git-scm.com/book/en/v2/Git-Tools-Debugging-with-Git
For example,
git blame -L 174,190 xx.py
