terminology - foo, bar, baz 等的含义

Question

我一直想知道 foo、bar、baz 等... 名字的意思。

我曾多次在科学文章中发现这些术语。此外，该术语以某种方式用作其他示例的标准。

有谁知道这些术语的来源，以及如何正确使用它们？

虽然这个问题超出了 Stack Overflow 的范围，但我强烈推荐维基百科关于这个问题的文章:

The word foo originated as a nonsense word from the 1930s, the military term FUBAR emerged in the 1940s... The term foo fighter was used by Allied aircraft pilots in World War II to describe various UFOs or mysterious aerial phenomena. The first known use of the terms in print in a programming context appears in a 1965 edition of MIT's Tech Engineering News.
