  • It's answered [here](https://stackoverflow.com/questions/34212049/meaning-of-foo-bar-baz-etc). Technically, they are made up names. They're just calling/importing stuff from the files `one`, `two`, `three`. – samkart Oct 15 '19 at 06:23

  • It's just an example functions' name. Nothing specific. – Saharsh Oct 15 '19 at 06:24

It's a metasyntactic variable.

These names are often used as example variables. On python, ham, eggs and spam are used too. Wikepedia says: https://en.wikipedia.org/wiki/Metasyntactic_variable
