One tradition I'm happy got lost in the way is using FOO, BAR, BAT in examples. It made the simplest examples hard to understand and those words never made any sense to me.

It's always better to use contextual words in most examples.

edit: for more clarity this article (1) explains it quite well

I'd honestly rather have a,b,c than that! Nobody writes code with such placeholder variable names, so why demonstrate it that way?

Placeholder variables like i and j don't count! Foo, Baz, etc are annoying to read too, IMO.

I use foo, bar, baz, etc. all the time when I’m writing tests. But I agree generally it is better when examples use meaningful name `cd /path/to/file` as oppose to `cd /foo/bar/baz`

What's wrong with FOO? It's fun to say and can use it almost anywhere when you need a random word. Has saved me seconds here and there when I didn't need to think of a word because I have FOO :)
