@h3mmy @rootsandcalluses is this the way to pedantry corner? Shall we head there together?
Camel case is the first letter of every word after the first capitalized. #camelCase. The first letter of every word, including the first is Pascal case: #PascalCase.
These are both terms of art in programming. Pascal case, in particular, comes from the Pascal programming language.
Title case is different in that minor words aren’t capitalized, and is used in literature (sort of, certainly not programming) for titles and headlines:
Netizens Discuss Capitalization in Pedantry Corner: Homo sapiens Mid-conversation Share
The above title confioms to the Chicago Manual of Style (whose title also conforms) by not capitalizing 4 of 11 words.
Now to make this useful: both camal case and Pascal case address the issue at hand; title case doesn’t, but the expression may be useful to communicate the idea of Pascal case to a general audience.
