Agreed.
I am a Ruby person (obviously by user name, haha), I do not use the term “dictionary” referring to arrays and objects and so forth, at least for me, using the term “dictionary” is (overly) programming language specific.
JSON, is the “programming language neutral” term, and “map” seems to me (as mentioned) is referring to mapping a token (“key”) to a value (in this case a float / real).
