Foobar
placeholder names in programming From Wikipedia, the free encyclopedia
Foobar, and sometimes foo and bar separately, are common placeholder names in computing.[1]
Foobars have been used to name variables, functions, and commands whose exact identity is unimportant. For example, a JavaScript tutorial might explain that two variables can be created at once with the code var foo, bar = 5. It's a lot like the placeholder letters x and y in algebra.
