git: using blame to see when a line was modified

In VSCode, there’s a built in git blame feature that will allow you to inspect who is responsible for the last change to a line.

This is also possible from the terminal:

% git blame -L 12,25 foo.js

In this case I ran the blame on a javascript file, foo.js for lines 12 through 25.

The output takes the format of: [hash] [file] ([author] [date]) [change].
