The terms foobar (/ˈfuːbɑːr/), foo, bar, baz, and others are used as metasyntactic variables and placeholder names in computer programming or computer-related documentation.[1] They have been used to name entities such as variables, functions, and commands whose exact identity is unimportant and serve only to demonstrate a concept. The style guide for Google developer documentation recommends against using them as example project names because they are unclear and can cause confusion.[2]
